In this episode of In the Kitchen with Matt, I will show you how to make sugar glass. This easy edible glass recipe is awesome! It takes very few ingredients. You can make movie props, fun decorations, use it for Halloween, whatever you like. :) You could get some silicone molds and make candies with it. Glass candy lego men, green glass Christmas trees, got nuts! It looks like glass, it behaves like glass, it is sharp like glass, but you can eat it! If I can do it, you can do it. Let's get started! :)

Don't forget to follow me and check out my other Instructables. :)

Follow the easy steps below or watch the video tutorial or do both. :)

Step 2: Water, Sugar, Corn Syrup and Cream of Tartar

First add the water, sugar, corn syrup, and cream of tartar to a deep pot or skillet.

Step 3: Prepare the Pan

Now prep a sheet pan with a silicone mat or spray the pan with kitchen spray. You could also use aluminum foil as a liner. Spray the foil as well. We don't want the sugar glass to stick to the pan.

Step 4: Stir and Heat

Now we place the pot on the stovetop and set the heat to medium-low. Stir gently until the mixture starts to boil. We want to get the candy up to the hard crack stage, which is right around 290 F to 300 F. (150 C). But, we don't want to heat it up too fast otherwise it will get too dark. My thermometer is old and doesn't register the heat properly anymore. After the mixture starts to boil you can stop stirring and let it heat the rest of the way. If you don't have a candy thermometer pull off the hot sugar right when the mixture barely starts to turn color, yellowish color. Also, I usually turn up the heat to medium after it starts to boil. You can see in the third photo it is an amber color. It will still work, but harder to color when it is this dark. Once it has gotten to the proper temp remove the candy from the heat and add in any food coloring or flavored extracts.

***Please be very careful this mixture is tremendously hot. If you are a young child please have adult supervision while making this.

Step 5: Pour and Wait

Next just pour out the candy onto your pan and allow it to spread out. Make sure the pan is level. The thinner you spread it out the thinner the glass will be. Then wait for it to set. This usually takes an hour or two.

Step 6: Check Out That Sugar Glass

Now we can check out the sugar glass. It is incredible. It looks like glass, it feels like glass, it shatters like glass, it is sharp like glass. But it is edible and tastes super yummy! haha.

Step 7: Breaking Bad Blue Glass

Any Breaking Bad fans? This glass I took off the heat right when the mixture started turning color. It took the color very nicely. I should have poured this into my lego molds! haha. By the way, it tastes very similar to a jolly rancher if you are familiar with that candy.

Step 8: Clear Glass

And if you don't color it, it should turn out similar to this. Nice and clear with a hint of yellow.

Step 9: Burned Sugar Glass

Or you could wait longer and get it really dark. So even if you burn it or wait too long it will still work, it winds up looking like the color of a beer bottle. But it doesn't taste very good at this point.

Step 10: Video Tutorial

There you go! Awesome edible sugar glass. :)

Now check out those steps in action by watching the video tutorial. :)

    Question 4 weeks ago on Step 4

    Do you achieve your 150 degrees Celsius on a normal stop top?

    1 answer

    Yep with the heat set to medium-low to medium heat. Or you can use something like a hot plate as well.

    About 15 years ago my daughter made sugar glass as a science fair project. We both had a lot of fun with the process. But the best part was her in-class presentation. We had poured the sugar glass into a 10" round cake pan. When cooled she carefully wrapped the "glass" disk in clear plastic wrap to keep it from getting sticky in the Memphis humidity. As she began her presentation she was careful not to disclose that the "Glass" was wrapped in plastic wrap. At the end of her class presentation, she asked the class if they wanted to taste the sugar glass. With a room full of curious 13-year-olds the response was an enthusiastic yes. At that point, my daughter faked a stumble, the "Glass" fell from her hands and dropped onto the floor. Her fellow studendents looked on in shock and disappointment. The "Glass" had broken into a hundred small pieces right before their eyes. But since it had been secretly wrapped in plastic the sweet treat was still safe to consume. She picked up the disk and unwrapped it and shared the glass candy with class. I think her pratfall was the talk of the 7th grade for the rest of the year. She got an "A" for the project and the presentation.

    What is the purpose of the cream of tartar?

    1 reply

    Hey there, it helps the sugar be more stable once it is melted, and not re-crystalize. It is an optional ingredient. You can certainly make it without it. :)

    Question 4 weeks ago

    Hi, nice project. Do you know if, and how, it can be cut to shape? I was thinking of making a sort of stained glass window which could be broken and eaten.

    Thank you! :) The easiest way would be to have a mold of some sort. But what you could do is after it has cooled a bit, come in with a knife and score it. It will help it to break in the right places. A stained glass window would be awesome. You could use royal icing as the glue! :)

    Beautiful work and I am a huge Breaking Bad fan, so extra points there! Coincidentally, my manicurist just told me he saw a baking show where they made sugar glass and it made him really want to break it into bits. I want to make his dream come true BUT!!! Can I make this and let it sit for, say, 4-6 hours, then take it to his shop to break? Or will there be a point that it sits too long and it won't break as nicely? Probably the weirdest question or visual ever. Let my manicurist break glass!!!!!!!!!!!! :D

    Thank you!! Hehe so am I! :) I dressed up as Walter White last year for Halloween. Sure you can make it and let it sit for 4 to 6 hours no problem. :) It will break just fine.
