Cashew Brittle

I like this quick and easy recipe because it doesn't require a candy thermometer. It also makes a wonderful gift for nut lovers on your list. —Rhonda Glenn, Prince Frederick, Maryland

    Horrible!!!!! The 1 cup of sugar with 1/2 cup Karo. never did soften up...big huge rock hard mess. Had to ditch and try to salvage on stove. What a joke.

    Fantastic recipe! If you follow the directions exactly, you will have a delicious treat that is much easier and less hassle than making it on the stove top using a candy thermometer. I recommend a glass bowl to prevent sticking and also to soak the bowl in very hot soapy water immediately after pouring out the mixture onto the pan. I always avoided making brittle but thanks to this recipe I will be making it often.

    I was making this at my boyfriend's house and it must have cooked WAY faster than the time stated. Burnt way before cooking time was over and ruined his microwave bowl, Needless to say I did not finish making it, but don't think I will attempt it again.

    This is my most requested recipe I make for Christmas. Make sure not to add any more than one teaspoon of butter or it will not harden.

    This is wonderful, fast and easy. I've made it for several years now. I often substitute peanuts for the cashews and I adjusted the cooking times as I have a 1200 watt microwave. I used slightly less cooking times. Turns out perfect every time!!

    Due to variations in microwaves I would not use this recipe.I cooked it longer than called for because it never turned an amber color.It was a rubbery mess !

    I followed these directions exactly and found the result to be a sticky candy that never did completely harden. The solution is to extend the initial cooking time from 3 minutes to 4 minutes; add the cashews and cook for 3 minutes rather than 2 minutes; add the butter and vanilla; heat for another 1 1/2 minutes; then add the baking soda, stirring until very light and frothy. Spread evenly on a buttered cookie sheet and you'll have a true brittle.

    followed recipe and realized there was no water. Anyone know how much would be needed? I would like to make it and have it turn out correctly. Thanks for input.
