Why does my peanut butter fudge turn all crunchy and sugary
it is supposed to be creamy
You took it past the "soft ball" stage and let it get too hot, so the sugar re-crystalized. You may need a new candy thermometer, or perhaps use a heavier pan when you make it.
because you didnt stir it enough
Maby you need to leave it in in less time
You must use a candy thermometer in order to make candy, or at least until you get more practice. Good luck! Keep up the good work and you will be even more popular.
Because you made peanut brittle!
