  • 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. Continue to cook, stirring occasionally until mixture reaches 300ยบ F on a candy thermometer. Immediately remove from heat and add butter, baking soda, vanilla and peanuts. Stir quickly to combine and then pour onto buttered baking sheet.

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.
