Jo and I have been doing lots of projects over the last month or so for Little Jo’s birthday party, and I want to show you one of the projects I did for part of the party decor. We found ourselves needing some round gems in just the right color of teal. If they could be edible, all the better. So I did some shopping and some research and came up with everything I needed to make hard candy jewels. And I gotta tell you, this turned out to be one of the most fun projects I’ve done in ages!

By the way, there was a lot of trial and error as I figured out just the right techniques for making hard candy, and I’ll tell you about that at the end of this post. But for now, here is the right way to do it!

You’ll need to pick up a couple of custom supplies for making hard candy. First, you’ll need some hard candy jewel molds. Then you’ll need some liquid food coloring that’s suitable for use with hard candy and optionally, some candy flavoring oils in any flavor you like (although I left mine plain, and they tasted kind of like cotton candy!) The rest of the items you’ll need are quite simple: corn syrup, sugar, water, a pan, non-stick cooking spray, a candy thermometer, and a Pyrex 4-cup measuring cup.

Before we even think about turning that stove on, we’ve got lots of prep work to do. The prep will make this so much easier, so get everything ready to go before you start. The very first step, before you do anything else, is to calibrate your candy thermometer. You may not know that your thermometer can get “off” over time, especially the ones with the little paper guide inside that can move. If your numbers are off, you’ll never get the right temperature, and your candy might fail miserably.

Fortunately, it’s very easy to calibrate your candy thermometer. Just bring a pot of water to a boil and put the thermometer inside. It should read 212 degrees F (at sea level, anyway). If it’s higher or lower than that, then remember that difference and adjust your target temperature accordingly for this candy recipe. (For example: if your thermometer says 200 when the water is boiling, you’re 12 degrees too low, and you should subtract 12 from your recipe’s target temperature.)

I urge you to please not skip this calibration step, because it can save you so much frustration. I learned this the hard way (as you’ll see below) with candy that was overcooked and discolored!

Once your thermometer is set, then you need to spray the molds with the non-stick cooking spray. I put my molds in the sink to keep from spraying my counters. Don’t be too stingy, but don’t let it puddle, either.

Next, you want to cover your work area with aluminum foil. The candy won’t stock to the foil, so it’s a great surface to work on. Put a piece of aluminum foil on the counter next to your stove, making sure it’s close enough to catch any candy drips later. Put the Pyrex measuring cup right on the foil. Then put another big piece of foil on the counter and put your molds on top. If you’re going to use flavoring, get a clean, dry spoon ready and put it next to the Pyrex cup.

Now go ahead and mix up your ingredients in the pan. You’ll need:

  • 2 cups granulated white sugar
  • 2/3 cup light corn syrup
  • 3/4 cup water
  • food coloring as desired (I used 20 drops)
  • 1 tsp (1 dram) of candy flavoring oil (optional)

Stir together everything except the flavoring oil so that it is mixed well and the color is uniform. Then clip your candy thermometer to the pan, making sure it does not touch the bottom of the pan.

UPDATE – I recently read that adding the coloring too early in the cooking process can make your candy turn out sticky (because the acid in the coloring will invert the sucrose), so despite what these pictures show, you may want to wait and add the coloring at the last minute with the flavoring.

Okay, all set? Everything greased and covered and set up and ready to go? Then go ahead and turn the burner on high and get it going. The faster you cook this, the less chance of caramelization, so be sure the burner is turned up as high as it will go. By the way, do not leave this unattended. Stay put!

When the mixture first starts to boil, the temperature will rise to 212 really fast, and there will be lots of steam as the water boils away. If your thermometer is anything like mine, it will be covered with condensation and hard to read. That’s okay, though… you’ll see why in a sec…

As it continues to boil, you’ll see the the temperature rises much more slowly now. (Don’t use that as an excuse to leave, though… please stay and watch it for your safety!) You’ll also notice that the steam dies down as the water goes away, and soon there is no steam at all. You’ll also notice that your thermometer is suddenly dry and easy to read. Awesome.

Now this part is critical, so pay attention. Let the sugar boil to 300 degrees F but not a bit more! (I’ll explain why at the end of this post). The minute you hit 300, take the thermometer out and set it on the foil (aren’t you glad you had that ready?). Then immediately dump the boiling sugar into the Pyrex cup. We do this for two reasons. First, it’s easier to pour from the spout. Second, we want to stop the cooking process, so we need to get that liquid out of that hot pan or else it will keep cooking.

NOTE – This sugar syrup is VERY hot, so make sure your measuring cup is made of something heat-proof like Pyrex. Also make sure it’s at least the 4-cup size so that you have enough room for the bubbling liquid.

At this point, you can add your optional flavoring oil (and coloring, if you didn’t add it already), and stir it in quickly (but carefully!) with the spoon you had ready.

Now you’ve got to work pretty fast to pour the sugar into the molds before it hardens. You’ll have a few minutes of working time, so don’t trip over yourself to rush, but don’t waste time either. The candy syrup will be very easy to pour for about 5 or 6 minutes, and then will start to thicken up. After 8 or 9 minutes, it’ll be too thick to pour and you’ll be done.

Just pour the sugar slowly and carefully into the molds, taking care not to overfill them. Do your absolute best to not leave huge puddles or trails of sugar between the pieces, because they will be nearly impossible to remove later.

When you fill the “breakaway” molds (those with the pieces right up against each other), you need to be really careful not to overfill. If you cover up those little white lines between each jewel, I can pretty much guarantee that they will shatter when you try to break them apart later.

While you wait for the candy to set, let’s talk about cleanup. That pan looks awful with the caked-on sugar, right? Fortunately, all you need to do is fill it up with water and let it sit a few hours. Go ahead and toss the thermometer and spoon inside, too. The sugar will all dissolve after a good soak.

After five or ten minutes, your candies will be set. Just flip the mold over onto the foil and give it a gentle bend, and the candies should pop right out.

And that’s it, your candy jewels are done! They will have a slight film of oil on them, which will help keep them from sticking together, but you can wipe that away with a paper towel if you like. As long sure to store them in an air-tight container, they shouldn’t stick at all.

I just love how these hard candy jewels came out!

So you might be wondering what I ended up using these candy jewels for. They were the decoration on the Princess Peach birthday cake that I made for Little Jo’s Super Mario Brothers themed birthday party.

I’ve also used this recipe to create cinnamon-flavored candies for Christmas, to give as little gifts to friends. I put some in bags and some in clear glass bowls, and they look so pretty.

The film of oil on the candies (leftover from the greased molds) should keep them from sticking together, but if you want to be extra sure your candies don’t stick, you can toss them in a bag with a little bit of powdered sugar.

Once you brush off the excess, you end up with candies that not only won’t stick together, but that actually look like frosted glass!

I also used this recipe to make some sweet heart-shaped candies for Valentine’s Day. Be sure to check out my Valentine’s Day heart shaped candy tutorial for more info, including our free downloadable bag tag. There’s even a tip about making giant heart-shaped lollipops!

BONUS – lessons I learned

Now that I’ve shown you how to make these candies the right way, let me share with you some lessons I learned while figuring it out.

#1 – Don’t overfill the molds

Those molds are labeled as “breakaway” and you might think that you can just snap the candies apart when they are cool and everything will go great. That is not the case at all. If you put too much candy in the molds, you’ll end up with a huge slab of hard candy that breaks into every shape imaginable EXCEPT the one you were trying for! Here’s what happened to me on my first attempt. What a mess it made.

#2 – Don’t undergrease the molds

When I made my first batch of candy, I didn’t have any non-stick cooking spray, so I tried to just wipe some oil onto the molds with a paper towel. The result was a film of oil that was no where near enough, and the candies stuck like crazy. Take another look at the picture above and see the bits of candies stuck to the mold. Ugh!

#3 – Don’t overheat the syrup

You can get decent candies with varying temperatures, but for decent and true COLOR, you need to be sure you don’t heat past 300 degrees. Having an accurate candy thermometer is critical to the success of this candy, so please make sure you calibrate it using the instructions I mentioned at the start of this tutorial.

The first time I tried this candy, my thermometer was way off and I had no idea. My candy cooked way too long and the sugar started to caramelize. The syrup was yellowish by the time I added my blue food coloring, and the result was quite green! Then I tried again with a lower temperature, and it was still too much. Then I finally figured out my thermometer was wrong, and when I adjusted for that, I hit the jackpot with true blue candies.

NOTE – Colors like red/orange/yellow are pretty easy, because a little extra caramelization won’t mess it up, but if you’re doing clear or blue candies, or you really want true colors with no golden tint, you might want to stop the temperature a little shy of 300 degrees. Stopping at 295 or 290 will keep your colors true, but you also run the risk of the candy not setting up hard enough. It’s a very fine line, so you need to experiment to get the results you want.

Here’s a picture of the three batches I made with the exact same amount of blue food coloring, but I let them cook to different temperatures. Can you believe the difference? If you want your colors true and bright, be sure your thermometer is accurate and don’t cook it too long.

#6 – Have enough molds ready

There’s nothing more frustrating with this project than having extra sugar syrup leftover with nowhere to put it. So make sure you pick up several of the hard candy molds and prep them all so that you’re ready for however far your syrup takes you!

#5 – Don’t leave the syrup in the pan

As I mentioned earlier, you need to dump the syrup into another container when it has reached the proper temperature. Otherwise, the hot pan will continue to cook the syrup and you’ll go over the target temperature and it will start to turn yellow. If you don’t believe a few degrees will make that much of a difference, take a look at this picture of my pan. After I had dumped it out and made my candies, I went back and looked and the small amount of sugar left in the pan started to turn yellow just from sitting there. Discoloration like that will ruin a batch of candies fast!

    Tiana, if the candy is coming out dark, it’s because the sugar is being heat up too fast or to too high a temperature. Make sure you calibrate your thermometer as described above, and turn down your burner.

    Rizza, the type of candy thermometer I used here is available in most grocery stores or Walmart, and will cost around $5. Because this recipe calls for such exact temperatures, I would not suggest trying it without a thermometer.

    Hello ladies, thank you very much for all your advice and hints. Prior to coming across your website I tried making these candy gems and couldn’t work out how to pour accurately into the moulds. I ended up with the syrup hardening before I even spooned enough into the moulds. I am now looking forward to having another go, with more success this time round. Thanks again from down under.

    Chica and Jo, Here’s a great tip: If you have candy over the edges of your moulds, spray a dough scraper (metal) with non-stick cooking spray and drag over the top of each mould. (It works amazingly). Also, if you want your hard candy not break down from humidity, place a 1 ounce silica gel packet in your ziplock bag or plastic container. This also works wonders and you don’t need powdered sugar to keep it from sticking. And lastly, if you cook the liquid 290- 295 degrees F to prevent the sugar from hardening, place the tray or moulds in the fridge for 30 mins. or until completely hardened.

    Bridget, thanks so much for all the tips. I especially love the silica gel idea. I save those packets all the time.

    Bridget 09/26/2015 at 9:16 pm

    I forgot to add that if candy is placed in fridge for 30 mins. to prevent yellowing if cooked between 290-295 let sit for 10-15 minutes before packaging, The silica gel packets should take care of any excess moistureuse. I use (3) 1 oz pkts per 1 lb of candy. Make sure to remove as much air as possible before sealing ziplock bag. Candy can also be put in a plastic storage container with a sturdy snap lid like Rubbermaid. Packets should be placed on top of the candy if using a plastic container. You can buy 200 packets through Amazon for approximately $10 (I’m a professional candy maker, so I buy things in bulk. I LOVE your glass house!

    This cake looks lovely! One question…I don’t have a candy thermometer, do I need one or can I do it without? Thanks for your help :)

    Freya, this recipe requires such exact temperatures that we really recommend you use a calibrated candy thermometer for best results. Perhaps a friend has one you can borrow?

    Freya 10/03/2015 at 6:04 am

    Hiya again! I’ve just made it! It looks good, but the pan doesn’t ;) Do I pour boiling water in and let it sit or cold?

    Wendy 10/03/2015 at 11:49 pm

    Hi! Thanks for such clear and concise instructions! Your jewels are stunning!! Silly question….can this recipe be used for candy apples?

  • 13
    Chica 10/04/2015 at 12:14 pm

    Freya, boiling water might speed things up a little, but the best thing to do is just fill the pan with room temperature water and let it sit overnight. The sugar will all dissolve by morning.

  • 14
    Chica 10/04/2015 at 12:19 pm

    Thanks, Wendy! For apples, we recommend you try the recipe we have in our candy apple tutorial. It’s slightly different.

    A while back I purchased a 750g tub of Isomalt. I had a go at using it a couple of days ago. First time it turned out yellow, second time I burnt it but on my third attempt yippee! beautifully clear. The first couple of goes I placed in a saucepan about 4 tablespoons of the isomalt but because it didn’t work so well I tried it in a pyrex jug in my microwave. This time 8 tablespoons. High power for about 30 seconds. Swirled it about. Another 15 seconds. Swirled it about. just keep going until the mixture is clear. (Be very careful as the glass jug becomes very hot). I used a kitchen tea towel. so I wouldn’t get burnt. Wait for the bubbles to pop and then pour into your moulds. I did use silicone moulds and the decorations I made popped out fine when they were cold. To get rid of the remaining bubbles I had, I used a blow torch but only swept it across as I didn’t want to loose detail. My decorations are now stored in a tin. I am from the uk and I haven’t used the silica packets to store my items. I have used from my biscuit barrel a metal container which absorbs moisture.

    Hi! Can you use the silicone molds or plastic molds made for jello.

  • 18
    Chica 12/03/2015 at 8:15 am

    Georgia Lynn, do not use plastic Jell-O molds, as they would surely melt. I have not tried silicone molds, but if the ones you have say how hot they can get, and it’s within range of the candy, it might work. Hard candy molds really are the best though!

    Bethany 12/09/2015 at 11:51 am

    I’m going to try to make stained glass window cookies. The recipe calls for clear candies and I didn’t really want the cookies to taste like jolly ranchers or life savers, so I thought about making my own candy, but I want multiple colors. Is it possible to add the color after you cook it or do you need to divide the recipe and make each color separately?

  • 22
    Chica 12/13/2015 at 10:29 am

    Bethany, you can definitely add the coloring at the end, but the trick will timing. The candy sets up fast, so if you want to separate it into multiple bowls and mixing several colors, you’ll have to move really quickly! If you don’t like the taste of Jolly Ranchers, you could always use lollipops or other hard candy that you do like.

    Megan 12/16/2015 at 8:00 am

    After three tries (and a new candy thermometer), I finally have the beautiful gem candies like these. Note: coloring red — have to adjust for the yellow/cook factor so they don’t have too orange/coral a hue. Similar to the green/blue issue you described here. Thank you!!!

    Chica 12/19/2015 at 12:02 pm

    Congrats, Megan, for sticking with it long enough to get it right!

    Trying this candy thing for the first time, since they are horribly expensive to buy and I need a bunch:)
    Question, I have one mold and I know for certain, I’m going to need it several times, I know I am going to definitely run the risk of my liquid solidifying -any suggestions other than buying more of the $9.99 molds

  • 26
    Chica 01/25/2016 at 6:39 pm

    Phelida, you definitely won’t be able to re-use a single mold more than once for one batch of candy. If you don’t want to buy additional molds, you could try cutting the recipe in half and make a smaller amount.
