Microwave Peanut Brittle

From Nana

1 cup raw peanuts
1 cup sugar
1/2 cup light corn syrup
1/8 tsp. salt
1 Tbsp butter
1 tsp. baking soda
1 tsp. vanilla

*In a 2 quart glass mixing bowl, mix peanuts, sugar, corn syrup, and salt. Cook on high (in microwave) for 3-1/2 minutes. Stir well, then cook another 3-1/2 minutes. Add butter and stir well. Return to microwave for 2 minutes.
*Quickly remove from microwave and stir in baking soda and vanilla; mix well. Pour onto a greased cookie sheet (or pizza pan). Spread out evenly and let cool/harden. Break into pieces with knife.

**Variation: if making pecan brittle, only cook for 5 minutes (instead of 7) before adding butter.
