    Sorry it didn't turn out for you. Every microwave is going to run slightly differently if the mixture is starting to turn slightly brown then you shouldn't microwave it any longer as stated.

    I followed the directions exactly as written and should have stopped after the first microwaving. The second microwaving resulted in a burning of the syrup and sugar mixture and I wasted the whole batch!

    I'm going to try this recipe today, but my concern is cleaning the glass mixing bowl and utensils I'll be using. Won't the mixture harden on them, too? How do you clean them properly?

I've learned that brittle is better when made on a cool, dry day. When I've made the candy on a warmer, humid day, it tends to be a stickier brittle. This is because the brittle takes longer to cool, and it reaches a point where it is no longer evaporating moisture into the air.
