    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.

  2. Microwave Peanut Brittle Recipe-Butter Your Biscuit (8)J

    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?

Why isn t my peanut brittle crunchy? ›

Why is it too hard? Using baking soda usually prevents peanut brittle from being too, well, brittle. However, if you cook the candy past the set temperature or overwork the candy once you spread it out onto the cookie sheet, that can cause it to become very hard and difficult to bite through.

Low and slow. Simmering the syrup for English toffee to the requisite 300°F temperature can (and should) be a slow process — up to 20 minutes or so.
