Instructions
- Step 1: Combine ingredients Combine the water, corn syrup, sugar, and cream of tartar in a large saucepan. Stir to combine them and heat them slowly over low heat.
- TIP: If the heat is too high, the sugar mixture will caramelize and turn brown.
- Step 2: Heat to hard-crack stage Use a candy thermometer to bring the mixture up to the hard-crack stage — around 290 to 300 degrees Fahrenheit.
- TIP: Carefully mix in a few drops of food coloring to create a stained-glass appearance.
- Step 3: Spray sheet pan Spray a sheet pan liberally with a nonstick cooking spray or use a silicone mold if you have one.
- Step 4: Pour the sugar mixture Pour the mixture into the pan quickly and evenly as it will start to set as soon as it is removed from the heat — be careful and avoid being burned.
- Step 5: Shake the pan or mold Shake and tip the pan to get even coverage and to level the mixture. Wait an hour for the candy mixture to cool completely.
- TIP: Use a pin to pop any bubbles so the glass has a smoother and more convincing texture.
- Step 6: Remove glass Remove the sugar glass from the pan by dragging a hot knife along the edges and then prying it up. A silicone baking mat should fold back and release more easily.
- Step 7: Refrigerate until ready Refrigerate the sugar glass until it’s ready to use. Enjoy your prop glass while it lasts.
- FACT: The first nuclear bomb test in New Mexico created a crater 800 yards across and melted the desert sand into a gray-green glass shell called trinitite.
