Microwave Peanut Brittle

Kathy Sterling


Back in the early 1970's I got my first Microwave. It was big and costly, but I "had" to have one. Of course now we can't live with out it.

I remember taking a cooking class on how to use one. I don't think I did much at first, except warm food, which is what we use it most for today.

My Fridgidare microwave came with a small recipe book and this Microwave Peanut Brittle recipe was included. I tried it and was hooked. So for more than 30 years I have made peanut brittle this way, and it is as good as ever. Quick, easy and tasty...Enjoy!
