  • Add sugar, corn syrup, water, and salt to a medium, heavy-bottomed saucepan. Stir to combine and then cook over medium heat about three minutes, do not stir.

Notes

Store in an airtight container for up to 2 weeks.
If you do not have a candy thermometer, you can test your peanut brittle using a cold water test. Drop a small amount of the sugary syrup into a small bowl or glass of very, very cold water. The syrup with solidify, but will still easily separate into hard, brittle threads.
