Step-by-step tutorial
Step 1
Spread the powdered sugar over a metal baking sheet. Sprinkle 1 tbsp of citric acid over the powdered sugar.
Step 2
Measure out the other 2 tbsp of citric acid into a small bowl and set it aside.
Step 3
In a medium saucepan, add the granulated sugar, the water, and the corn syrup. Place the saucepan of the medium heat.
Step 4
Stir the mixture until it boils. Then stop stirring and wait until the mixture just starts to turn brown at 305 degrees F. This will take about 5 minutes.
Tip
Watch this step very carefully - once the sugar starts to brown, it will burn very quickly.
Step 5
Remove the pan from the heat and let it cool for 3-5 minutes, or until the bubbles subside. While it's cooling, measure out the baking soda, food coloring, and flavoring oil into a small bowl.
Step 6
Add the baking soda mixture to the pan and mix until combined. Be careful, the sugar mixture in the saucepan is still very hot.
Then immediately pour it out onto the powdered sugar you spread on the baking sheet. Sprinkle the remaining 2 tbsp of citric acid over the hot sugar. Let it cool to room temperature.
Step 7
Break up the cooked candy into small pieces with your hands or by crushing it with a rolling pin. Pop some in your mouth and feel the fiz! For maximum fizz, crunch the candy and then hold it in your mouth for a few seconds. Do the bubbles tickle your tongue?

What's going on?
This recipe keeps the citric acid and baking soda separate until you eat it. When these two ingredients combine with the saliva in your mouth, it creates carbon dioxide gas. It doesn't "pop" like the fizzy candy sold in stores, but you are still experiencing a chemical reaction in your mouth!
