Microwave Oven Peanut Brittle

    1 1/2 cups dry roasted peanuts
    1 cup white sugar
    1/2 cup light corn syrup
    1 pinch salt (optional)
    1 tablespoon butter
    1 teaspoon vanilla extract
    1 teaspoon baking soda

Grease a baking sheet, and set aside. In a glass bowl, combine
peanuts, sugar, corn syrup, and salt. Cook in microwave for 6 to 7
minutes on High (700 W); mixture should be bubbly and peanuts
browned. Stir in butter and vanilla; cook 2 to 3 minutes longer.

Quickly stir in baking soda, just until mixture is foamy. Pour
immediately onto greased baking sheet. Let cool 15 minutes, or until
set. Break into pieces, and store in an airtight container.
