I promise you will have so much fun with this edible sugar glass recipe. It looks like glass, behaves like glass, but it is candy!

Have you ever seen a movie where a piece of glass was broken over someone’s head? Or maybe it was a beer bottle or another kind of bottle that was broken? Or maybe you saw a person put glass in their mouth and they started chewing it? Chances are it was edible sugar glass. Are you a fan of the TV show Breaking Bad? Blue sugar glass or rock candy was used in that! It is so fun to make and the recipe is easy. You can make all kinds of things with it, movie props, bottles, a variety of candy shapes, or make an edible stained glass window held together with royal icing. You get the idea. If I can do it, you can do it. Let’s get started!

Step 1: Gather the ingredients and tools

In order to make edible sugar glass, you just need a few everyday household ingredients. No fancy ingredients are needed. You will need the following:

  • White granulated sugar – Sugar is the main ingredient in sugar glass? Imagine that.
  • Corn syrup – Liquid Glucose or corn syrup is used to help keep the sugar from becoming crystals again. It will help to make it more stable.
  • Water
  • Cream of tartar – this is an optional ingredient. But helps turn the sugar into fructose and glucose.
  • Food coloring – You will need food coloring to get your desired color or colors
  • Flavored Extracts – There are all kinds of flavored extracts that you can use.

Tools

  • bowl
  • pot or deep skillet
  • wooden or silicone spoon
  • sheet pan
  • kitchen spray or a silicone mat
  • candy thermometer (optional)

Step 2: How to make edible sugar glass

To begin, place water, sugar, corn syrup (liquid glucose), and cream of tartar in your pot or deep skillet. While the sugar doesn’t bubble up too high it is always a good idea to have something deep enough. A medium-sized pot works fine for this amount. But I generally just used my dutch oven or my stainless steel skillet.

Step 3: Prepping the pan

Next prepare the pan that you are going to put the hot liquid sugar “syrup” in once it is ready. I use a sheet pan lined with a  silicone mat. Or I just spray the pan lightly with kitchen spray. While I do love my silicone mat it will have a texture to that side of it. You can also use something like shortening on your pan.

Step 4: Stirring and heating the sugar

Now place the pot on the stovetop. With the heat set to medium-low gently stir the mixture until it starts to boil. It is important to not heat it up too quickly because the sugar is liable to caramelize. Which if you are making a dark glass it won’t matter. The goal is to heat the sugar mixture to the “hard crack” stage which is around 290 to 300 F (145 to 150 C). If you are using a candy thermometer make sure it still registers the correct heat. My thermometer is old and is several degrees off so I generally just eyeball it.

Once the sugar starts to boil you can stop stirring and just let it sit for 10 to 15 more minutes. Right, when the mixture starts to turn slightly yellow it is ready to go. Another way to tell is to drop a spoonful of it into a bowl with ice-cold water. It will instantly harden up and you can check out easily it breaks.

(boiling sugar, almost ready to take off the heat)

Don’t be alarmed if it takes awhile. This whole process takes somewhere between 30 and 45 minutes. Here is an example of what it will look like if you let it boil too long or too quickly. It will be a nice amber color. But you can still definitely use it at this phase.

Step 5: Remove the boiling sugar

Once you get the boiling sugar to the proper temperature, remove it from the heat. Then add in your food coloring and any flavored extracts that you want to use. Stir them in really well. The sugar cools quickly and thickens up quickly so you need to work fairly fast.

But BE CAREFUL this sugar syrup is extremely hot and will burn you if you touch it. If you are a young person please make sure you have adult supervision when making this.

Step 6: Pour and wait

Next, pour the hot sugar onto your prepared pan. If you want to make a pane of glass that will break when someone punches it or to hit someone over the head with it, make sure to pour it thin. Spread it out if necessary. Make sure the pan is level as well. Then wait until it hardens up. It usually takes an hour or two.

An optional step would be to pour the hot sugar into silicone molds. I have made some sugar glass lego men which were awesome! If you are going to go that route I recommend making a smaller batch and using a smaller pot, it will just make it easier to get into the mold.

Step 7: Check out your awesome edible sugar glass

Once your edible sugar glass has cooled it is ready to play with. It looks like glass, it behaves like glass, breaks like glass, but it is definitely candy! Oh and more thing it is sharp like glass! So be careful. Use a mallet or something to crack that glass.

Step 8: Breaking Bad blue edible sugar glass and others

Any Breaking Bad fans? Instead of using the candy thermometer I took this batch off the stove right when it barely started to turn color. The blue food coloring worked perfectly. Doesn’t this look awesome?

Or if you don’t want to color it at all you can leave it as is and get a nice clear glass.

What if I burn my sugar can I still use it?

Yes! If you happen to walk away and come back and find that your sugar has gone beyond that hard crack phase and it looks burnt and smells burnt. You can still use it!

How do I store sugar glass?

Generally, it is best to use it within a few hours if it is in sheets. Because it can tend to warp as time goes on. I normally will just put the pieces in a ziplock bag and put them in my pantry. They can stick to each other though.

How does sugar glass taste?

Sugar glass tastes very similar to a jolly rancher if you have ever tried one of those, depending on the flavor used. It melts very easily in your mouth. Homemade lollipops anyone?

  1. If I took it off too soon can I put it in the oven

    Had dinner at a 3-star Michelin restaurant in London this week. Stunning dessert was topped with what looked like tinted glass – they wouldn’t give me their secret. Came home and found your recipe – now I’ve made blue 3-Michelin star sugar glass for myself and adorned a a ‘Frozen’-themed pavlova. Everyone stunned! Thank you, Matt!!! :))

    Hey I just made this and it worked perfectly! I’m planning on using it on a cake as decoration. I’m just curious as it’s the 25th of April and the party is in June, how long can I store it for? Not talking about melting wise and such, I mean will it go bad, mouldy, make you sick after a while, that kind of thing? Like can I store it in my fridge for months? Thank you πŸ™‚

    • Hello, Madeline. Store the broken pieces or big pieces if you didn’t break them, in like a ziplock bag, but the pieces should be touching otherwise they will stick. They should last quite a while. They won’t go bad, it is just sugar/hard candy. πŸ™‚ It can be stored the fridge and at room temp, provided your house isn’t super warm inside. πŸ™‚

    I used your recipe to pour over ice. I couldn’t get it to the hard crack so I thought, maybe my thermometer is off. So I poured it over the ice. It was sticky and started to melt. So my husband and I pulled all of it off the ice and stuck it back in the pan and did it again. Well I didn’t realize my candy thermometer had a slide where it would actually attach to the side. Duh. So my fault I wasn’t getting a good reading. 2nd time was able to get it to a hard crack and poured it over ice and it worked fabulous. I am wondering how to store it. I have my grandson’s birthday coming up on the 3rd and we are driving 4 hours with the cake. I figured it would be okay to since it is candy now. I did put peppermint in it but my husband couldn’t taste it.

    • Awesome, Toni glad you gave it a try and were able to troubleshoot it. Are you sticking it to the cake? It should be okay for 4 hours on the cake. If not, store it flat in large ziplock bags. I wouldn’t stack them, because they will probably stick to each other. πŸ™‚ You can adjust, and add more of the extract next time, if that amount you used wasn’t strong enough. πŸ™‚

  5. Hi, I haven’t tried your recipe yet, but I was wondering if it would work to use glucose syrup instead of corn syrup. Cant wait to try this!

    • Hi Phoebe, we don’t have glucose syrup here in the States, or it isn’t common, since we have corn syrup, so it is hard to say. I haven’t tried it with glucose syrup, but that is very similar so I am guessing it will work just fine. Technically you can make it even without the corn syrup and just use sugar and water, but the resulting sugar glass won’t turn out as well. Good luck, let me know if you wind up trying it and how it turns out. πŸ™‚

    Hi Matt, can you tell me which food colouring you used and how much, I want the same shade as what you made.
    I have made some and although I put plenty in, it’s a greenish colour.

  7. Thank you for this amazing step-by-step! Quick question: have you tried free-handing a design (rather than using a mold)? I’m needing to make a 3-dimensional tree…and thinking about ATTEMPTING to drizzle it freehand. Is this something you’ve tried? Thanks again! I can’t wait to try it!

    • Hi Maura! No, I have only ever used molds. I would allow it to cool until very thick and then try it though, otherwise, it may not keep its shape. Reminds me of making drip sand castles back in the day at the beach. Maybe keep it in the pot to cool, and then drizzle some down, onto parchment paper. Place it in the fridge or freezer for a few minutes to harden a bit. Then drizzle more, etc. That method may work. Good luck! let me know how it turns out.
