Found this recipe at "alt.cookie.yum.yum.yum" and thought it sounded like it would be really good. Considering that I wouldn't have to hunt for Peanut Brittle this time of year, because I have best and easiest recipe ever.
I got the Microwave Nut Brittle recipe from my husband's Aunt Ruthie. She was kind of out of the family loop due to a divorce and being the one that was married in. She still tried to be family the best way she could. She gave me a microwave cookbook for a wedding present. She loved to cook with her microwave and encouraged me to do the same. The one recipe she circled and wrote "VERY GOOD" next to was the Microwave Nut Brittle recipe. I tried it right away and it has been one of my favorites ever since. In about 12 minutes you can have Nut Brittle cooling. With the invention of the Silpat, a non-stick baking mat, it's even easier as this recipe does SO well on a Silpat. I must add that my microwave is an old grandpa and about 23 years old. Still going strong, but has a power of 700 watts. Today's microwaves are nearly double that. So, make sure you keep that into account when doing this recipe. I'm not really sure how it will affect your recipe as I haven't used the newer microwaves, but this link might help.
