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 cashews. Microwave at hight 3-5 minutes, until light brown.
Add butter and vanilla to syrup, blending well. Microwave at hight 1-2 minutes more. Cashews 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.
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!
