Ingredients

2 cups granulated sugar
1 cup light corn syrup
1/3 cup water
16 ounces of roasted or raw peanuts shelled
1 teaspoon salt
2 teaspoons butter
2 teaspoons baking soda

Instructions

Line a baking sheet with parchment paper or a non-slip baking liner.
In a pot, combine sugar, corn syrup and water. Cook over medium-high heat until it boils.
Reduce heat to medium and carefully attach candy thermometer to the pot, taking care that the thermometer is in the liquid and not touching the bottom or side of the pot.
Continue boiling, stirring occasionally, until candy thermometer reaches 250 degrees F (around 20-30 minutes).
Stir in peanuts and salt.
Cook until the mixture reaches 295 degrees F (can take anywhere from 15-30 minutes).
Remove from the heat and immediately stir in the butter and baking soda. It’s at this point that the mixture will change colors. (You will also see it foam. This is completely normal!)
Immediately pour the mixture onto the prepared baking sheet and spread with a spatula.
Cool completely and then break into bite-sized pieces. Store leftovers in an airtight container away from moisture.

Notes

Cooking time will vary based on altitude and other factors, so watch the candy thermometer instead of time!

We have also used raw peanuts in our peanut brittle, but just know that you have to cook raw peanuts before you eat them. (You can't eat them from the jar like roasted peanuts.)
