Why Did My Peanut Brittle Not Get Hard

The key to peanut brittle is ensuring you cook it long enough. If you don’t cook it long enough you will end up with a soft sticky mess that doesn’t harden properly. The mix has to get to the hard crack stage, or else it won’t work.

You will find the strands of sugar harden fast and break easily, instead of feeling sticky.

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? ›

Baking soda is also very important at this stage since it reacts to the heat, creating carbon dioxide that aerates the caramel, enabling it to snap when someone bites into it rather than requiring them to gnaw at it until it breaks or pulls apart.

How do you keep peanut brittle crispy? ›

The candy will attract moisture from the air, making it unpleasantly sticky instead of shatteringly crisp. Once it's completely cool, transfer it to an airtight container.

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.

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 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.

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 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.

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: 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.

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.

How long does homemade peanut brittle last? ›

Properly stored (in an airtight container at room temperature), peanut brittle will last one to two months.

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.

Can peanut brittle spoil? ›

Unopened store-bought peanut brittle, when stored in a cool and dry place, can easily last 6-9 months past the 'best by' date printed on the packet. Once opened, you should aim to eat it within 1-2 months to enjoy it at its best quality, but it may still be safe for consumption after this time.

Is peanut brittle supposed to be hard? ›

Peanut Brittle is a smooth, flat candy (similar to toffee), with peanuts in it, that is cooked on the stovetop and poured onto a sheet pan to cool. Once it cools it's broken into small individual-size pieces of hard candy and lasts at room temperature for several weeks.

Why did my peanut butter fudge not get hard? ›

If you didn't reach the correct temperature during the cooking process, it might not set properly. Use a candy thermometer to ensure that you reach the recommended temperature. Overcooking or Undercooking:Solution: Cooking the fudge for too long or too short a time can affect its texture.

Why is my peanut butter fudge not hard? ›

The amount of time you cook fudge directly affects its firmness. Too little time and the water won't evaporate, causing the fudge to be soft. Conversely, cook it too long and fudge won't contain enough water, making it hard with a dry, crumbly texture.
