Frequently Asked Questions about making Mom’s Best Peanut Brittle

where can i buy raw peanuts?

At the local grocery store and online. I have found them in the baking section at my grocery store. Others have bought them from Trader Joe’s, from the produce department of their grocery store, a farmer’s market, and even from a peanut farm.

when using a candy thermometer, what temperature do you bring the boiling mixture to?

Hard crack stage, which is between 300-310 degrees. If you don’t have a candy thermometer, stir the boiling mixture until it spins a thread when drizzled from the spoon. It sounds crazy, but you’ll know what I’m talking about when it happens. See the step-by-step video towards the beginning of the post for an example of what it looks like.

can you use other types of nuts in this recipe?

I have only used raw peanuts, but I don’t know of any reason why other nuts would not work. A couple of readers used almonds, and it turned out good for them.
