This is a recipe for your microwave. It's a great one and so easy.
In 1 1/2 quart microwave safe glass dish stir together sugar and corn syrup. Microwave on high for 4 minutes.
Stir in peanuts. Microwave at hight 3-5 minutes, until light brown.
Add butter and vanilla to syrup, blending well. Microwave at hight 1-2 minutes more. Peanuts will be lightly browned and syrup very hot. It will turn a bit darker brown. That's when it will be done.
Add baking soda and gently stir until light and foamy.
Quickly pour mixture into lightly greased cookie sheet or unbuttered non-stick coated cookie sheet. Let cool 1/2 to 1 hour. When cool, break into small pieces and store in airtight container.
If raw peanuts are used, add before microwaving, to sugar-syrup mixture, along with 1/8 tsp. salt.
Madagascar Vanilla (purchase at Chefs Catalog) Of all the vanilla's I've used this is my favorite. Once you've tried it you won't go back!
