What does baking soda do in peanut brittle?

This is a peanut brittle recipe using baking soda because baking soda is a leavening agent. It creates a chemical reaction with the peanut brittle ingredients and foams. It’s what helps the peanut brittle become more light, porous, and softens the brittle to make it a little chewy. This is a fun science project part of cooking for kids!

To make proper peanut brittle (or any kind of candy), you definitely need a candy thermometer. (I like the ones that clip right to the side of your pot like this one.)

Peanut Brittle Recipe FAQs

How long does it take for peanut brittle to harden?

Once you’ve spread your peanut brittle onto parchment paper or a silicon mat to cool, it can take around 20-30 minutes for the peanut brittle to harden. Weather may affect the peanut brittle and if it’s more humid than it may take a little longer or may not harden completely.

Is peanut brittle supposed to be chewy?

Peanut brittle is supposed to be crispy instead of chewy. However, once you bite into the candy it becomes a little chewy. If your peanut brittle doesn’t harden and stays chewy, you may not have cooked it to the right temperature using a cooking thermometer.

If you’re wondering how to fix chewy brittle, it may be because you didn’t cook it to the right candy temperature.

What is the best way to store peanut brittle?

Once you have made the peanut brittle and broken it up, allow it to cool. Then, store peanut brittle in an airtight container, away from humidity and moisture. Do not store your peanut brittle in the refrigerator.

Does humidity affect making peanut brittle?

Yes, the moisture in the air can affect how your peanut brittle turns out. Also, it can make it sticky when stored. Be sure to store it in an airtight container at room temperature.

How do you break peanut brittle?

Breaking apart peanut brittle is one of the best parts of the process. Once cooled, you can turn the peanut brittle sheet over and break it apart with your hands. However, if you have kids helping, using a wooden mallet is a lot of fun! Just be sure that you show the kids how to break the peanut brittle into bite-sized pieces (and not smash it to dust!). Let the peanuts brittle cool first before breaking it up.

We like these mallets that you use for crabs or lobster to break brittle into small pieces.

That’s my daughter’s favorite part of this easy homemade peanut brittle!

Why is my peanut brittle too hard?

Are you wondering why isn’t my brittle peanut brittle recipe soft? The most likely reason your peanut brittle got too hard is because the cooking temperature was too high. It’s important to use a candy thermometer when making peanut brittle to get the right temperature for the correct consistency of the brittle mixture.

Why did my peanut brittle not get hard?

A homemade peanut brittle recipe can get sticky and stay a softer texture if you do not cook it long enough at the right temperature. Peanut brittle must reach a “hard crack stage” during the cooking. That’s why it’s important to use a candy thermometer for peanut brittle recipes to make sure it gets to 295-300 degrees F for the sugar mixture over medium heat.

Why is my peanut brittle sticky?

How do you keep peanut brittle from getting sticky?

Peanut brittle must be stored properly or it will become sticky. Do not store peanut brittle in the refrigerator. Store peanut brittle in airtight containers away from moisture in a cool place.

How To Fix Sticky Peanut Brittle

It can be sticky to fix sticky peanut brittle. (Sorry.) Sometimes you can reheat the brittle on the stove top or in the oven and melt it down to the heating point and then try to let it set to harden again.

You can make macadamia nut brittle, peanut brittle with pretzels recipe, or use items like pistachios, cashews, or even sesame seeds in their brittle! If you want to try it, just substitute them for the peanuts and make a no peanut brittle recipe!

Can you double peanut brittle recipe?

You can double a peanut brittle recipe, but it becomes more difficult because it takes longer to cook, may alter the peanut brittle recipe temperature, and then you have to work quickly to add the additional ingredients. Be sure to have all your ingredients measured and ready to go, along with the baking sheets and other supplies.

To be honest, I never double brittle recipes because it adds an extra element of difficulty. I don’t think this is a recipe you want to play the guessing game with!

IMPORTANT TIP: Before you start this cooking project, it is a must that you have a candy thermometerBest Recipe For Peanut Brittle (Old Fashioned Candy) (4) like this. You may be tempted to make this yummy easy peanut brittle recipe without candy thermometer, but just… don’t.

It was honestly the best peanut brittle candy recipe I’ve ever had — not too hard candy, but crispy enough — it’s not a super soft peanut brittle recipe. It’s a crunchy candy, but a peanut brittle recipe that won’t break your teeth!

You can also make it this peanut brittle recipe thin or thick, based on what you like!

We make peanut brittle recipe with raw peanuts (which is the perfect peanut for this recipe!), which makes it recipes with unsalted peanuts.

You can use roasted peanuts, too (or even make it a peanut brittle recipe with pecans for an old fashioned pecan brittle recipe, macadamia nuts, or any other nuts you love!).

Why put baking soda in peanut brittle? ›

Baking soda is a key ingredient in peanut brittle. It's what aerates the candy, giving it a nice light crunch. 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.

How do you keep peanut brittle crispy? ›

Should you refrigerate peanut brittle? Store the brittle in an airtight container at room temperature for up to 1 month to maintain the crisp. Moisture in the refrigerator would soften the brittle.

Why won t my peanut brittle get hard? ›

If your peanut brittle never sets up hard, it means you didn't cook it to a high enough temperature. Make sure you cook it to the “hard crack” stage, between 298°F- 313°F, and swirl your thermometer probe around in the syrup to get an accurate read of the temperature.

Why is my homemade peanut brittle chewy? ›

Why did my peanut brittle turn out chewy? The likely cause is that the sugar mixture didn't reach the proper hard crack stage temperature. Ensuring it reaches 300˚F is key to getting that classic brittle texture.

Why is my peanut brittle hard but sticky? ›

What's important to know is that the corn syrup controls the grain of the brittle so adding too little and you have a grainy textured brittle, while adding too much will result in a stringy and sticky brittle.

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.

How do you make peanut brittle hard again? ›

- Preheat your oven to a low temperature, around 250°F (120°C). - Break the stale peanut brittle into smaller pieces. - Place the brittle pieces on a baking sheet in a single layer. - Heat the brittle in the oven for about 5 to 10 minutes, checking frequently to avoid overcooking.

Can you overcook peanut brittle? ›

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. A thermometer is an accessible and inexpensive way to monitor temperature and ensure properly cooked brittle. Make sure your baking soda is fresh and active.

Should homemade peanut brittle be refrigerated? ›

To store: Store peanut brittle (once it's completely cooled) 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.

Does weather affect making peanut brittle? ›

I've learned that brittle is better when made on a cool, dry day. When I've made the candy on a warmer, humid day, it tends to be a stickier brittle. This is because the brittle takes longer to cool, and it reaches a point where it is no longer evaporating moisture into the air.

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.

What's the difference between toffee and brittle? ›

Brittles are typically composed mostly of sugar, while toffees contain a fair amount of butter and in some cases milk. This makes toffees fuller and richer in taste, while brittles are more purely sweet and sugary. Brittles are also much thinner than most toffees.

Can you use parchment paper when making peanut brittle? ›

You will want the cookie sheet to be non-stick. Use parchment paper, a silicone baking sheet or a greased cookie sheet. Spread the peanut brittle as thin as you can. Immediately add your sea salt.

What is the purpose of baking soda in candy making? ›

Baking soda helps to aerate brittle — it literally makes the molten candy bubble in the pot — to create a brittle with an airy, almost honeycomblike texture that crunches easily when eaten.

What does baking soda do in candy making? ›

The baking soda (also known as bicarbonate of soda) heats up and when it does that, it releases a gas that gets trapped in the caramelized honey and sugar. This results in bubbles that resembles actual honeycomb from bees!

Why is my peanut brittle bitter? ›

Those other liquid sugars have impurities that will burn at the higher temperature of making caramel, leading to a bitter-tasting brittle.
