With this instructable you can do some semi-complex chemistry in your very own kitchen with this simple recipe MICROWAVE Peanut Brittle. It's delicious, simple, and educational! If you don't like learning, ignore the science part, because this is fun and DELICIOUS!

Warning: WILL CONTAIN NUTS! (duh!)

Step 1: Ingredients

You Will Need:
1 cup sugar
1/2 cup corn syrup (preferably light)
1 cup raw peanuts
1/8 teaspoon salt
1 tablespoon butter
1 teaspoon vanilla
1 teaspoon baking soda

Step 2: Step 2

Combine the sugar, corn syrup, peanuts, and salt in a 2 quart microwavable bowl. Sorry, no picture of adding salt.

Step 3: Step 3

Microwave this on high for 8 minutes. Take it out half way through (4 minutes) to stir and put it back, stirring afterwords. Add butter.

Step 4: Step 4

Microwave again for 2 minutes (on High) and add the baking soda and vanilla. Stir until light and foamy.

Step 5: Step 5

Spread you mixture on a BUTTERED Cookie sheet as thinly as you can. Be sure to soak your bowl in warm (and preferably soapy) water to make it easier to clean.

The Science: The baking soda reacts with the other ingredients to harden it.

    I'll bet any syrup will do so long as the water content is low enough. Either way you should be able to cook the water out.

    One effect the corn syrup has which the golden syrup may or may not have is to help keep the sugar crystals dissolved and make the candy smoother.

    Hmm, what do I know, but I'm guessing sugar water, boiled down to make a sticky syrup, might work just as well.

    This stuff is super good. I have made it before and was thinking of posting it when I figured out it was already posted.
