Microwave Peanut Brittle

Thanks to Minette Greenman, who will always be loved as a beloved grandmother!

1 cup granulated sugar
1 cup peanuts (shelled)
½ cup white corn syrup
1/8 teaspoon salt
1 tablespoon butter or margarine
1 teaspoon vanilla extract
1 teaspoon baking soda

Directions: Lightly grease a cookie sheet. In a 1/1/2-quart-baking dish, combine the granulated sugar, peanuts, syrup and salt. Microwave the mixture on high power for 6 to 9 minutes or until brown, stirring well every 4 minutes. Add the butter or margarine and vanilla extract. Mix well. Microwave on high power for 1 to 3 minutes or until the mixture reaches the hard crack stage (300 degrees) when tested. Peanuts will be light brown and syrup will be very hot. Add the baking soda and gently stir until light and foamy. Pour the mixture onto the prepared cookie sheet. Let it cool for 30 minutes to 1 hour. When cool, break the peanut brittle into small pieces and store in an airtight container. Makes 1 pound.
