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.

FAQs

Why didn't my homemade peanut brittle get hard? ›

The main reason why peanut brittle doesn't get hard and have the crunch we expect is because the sugar was not cooked long enough. The sugar needs to be cooked to what is called the hard crack stage, 300ºF.

Why put baking soda in peanut brittle? ›

In theory, it's a good idea, the baking soda adds some air to the caramelized sugar, making the sheets of candy more brittle, but it also introduces a minerally, metallic taste that's off putting to say the least. My version of peanut brittle is ridiculously simple to make, and leaves out the baking soda.

How long does homemade peanut brittle last? ›

To store: Once it's completely cooled, store peanut brittle in an airtight container at room temperature. Do not refrigerate as the moisture from the fridge will cause the brittle to soften. Store for 6-8 weeks. To Freeze: Peanut brittle can be frozen and stored up to 3 months.

How do you make peanut brittle crispy again? ›

- Heat the brittle in the oven for about 5 to 10 minutes, checking frequently to avoid overcooking. Reviving stale peanut brittle is possible to some extent. You can try placing the stale peanut brittle on a baking sheet and gently heating it in an oven at a low temperature, around 250°F (120°C), for a few minutes.

Why is my peanut brittle not crunchy? ›

It's so important because if you cook your brittle much beyond the 300 degree F point, it could burn, and if you don't cook it long enough, the peanut brittle won't set as hard and be more sticky and chewy than crunchy and, well, brittle. Be ready to move quickly once the temperature reaches 300 degrees F.

What makes brittle hard? ›

What Makes it Brittle? The sugar will be cooked to 300ºF (149ºC)—hard crack stage; which when set up would be hard like a lollipop. But peanut brittle is delicate and you can easily bite into it—how? The secret is in the baking soda.

Why did my peanut brittle turn white? ›

Peanut brittle turning white, often referred to as "sugaring," is typically the result of crystallization of the sugar in the candy. This crystallization can make the brittle appear white or cloudy rather than having a clear, glass-like consistency.

Why is my peanut brittle not airy? ›

Working quickly, pour into prepared 10×15 pan. To keep the brittle light and airy, do not spread or flatten the mixture. Instead, let it flow freely. Place in a cool area and leave until completely cooled, about 2-3 hours.

Why is my peanut brittle bitter? ›

I don't recommend substituting honey, molasses, or agave for the corn syrup. Those other liquid sugars have impurities that will burn at the higher temperature of making caramel, leading to a bitter-tasting brittle.

Can I freeze homemade peanut brittle? ›

Absolutely! If you want to extend the life of your peanut brittle, you can freeze it. But, make sure it is completely cooled, as moisture is an enemy of peanut brittle. Ensure the brittle pieces are separated by parchment paper to prevent them from sticking together.

Can you overcook peanut brittle? ›

Use a candy thermometer!

If you overcook the brittle, it could be bitter or burnt. If you undercook it, the brittle won't properly set and the end result will be sticky.

Can peanut brittle be too hard? ›

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.

Why is my peanut brittle like taffy? ›

Didn't get it hot enough. You have to hit hard crack stage heat or it's not going to harden. From internet: Hard-Crack Stage is a cooking term meaning that a sugar syrup being heated has reached 149 – 154 C (300 – 310 F.) It is a test of how hot a sugar syrup is, and of how much water is left in it.

How do you keep peanut brittle from sticking to the pan? ›

Buttering the inside of the cooking pan will prevent sugar crystals from sticking to the sides while the corn syrup, water, sugar and butter cook to 275 degrees. At that stage the peanuts are added and the mixture is cooked, stirring constantly, until it reaches 300 degrees.

Why is my peanut brittle so thick? ›

Not spreading the mixture thinly enough: If the peanut brittle is too thick (usually because you used too small of a pan), it may not cool and harden properly. Be sure to spread the mixture as thinly as possible in the pan. 4. Humidity: Humidity can affect the hardening process of the peanut brittle.

How do you fix peanut brittle that's too soft? ›

So, I Googled Salvaging Undercooked Peanut Brittle and followed Tiffany's helpful instructions to throw the pieces back in the pan, turn the heat up and stir, stir, and stir to a raging boil and wait to pour it in the pan until it reaches 300 degrees.

How do you save peanut brittle that didn't harden? ›

Why are my peanuts not getting soft? ›

Dried peanuts will require a longer soaking time before cooking, so leave them to soak for at least 8 hours or overnight. Soaking the peanuts ensures that they will soften more easily when they are cooked, giving them their delicious texture.

How long does it take for brittle to harden? ›

Don't try to spread the candy once it's on the baking sheet as it starts hardening almost immediately and spreading it doesn't work well. Let the peanut brittle cool for 30 minutes, then break it into pieces. Store it in an airtight container at room temperature for up to two months.
