Hi back Jerry.

Wow 6 inches!
Seriously, Jerry, you should try it - super! Here's the recipe:
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
1. 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.
2. 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.
NOTE: You have to be super fast after taking the mixture out of the oven, b/c as it starts cooling, it starts hardening. The way I do it is have everything on the last steps pre-measured and ready to toss in. Then I spread it out as quickly as I can.
