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.

The general origin story of peanut brittle is that it came from the South, and that a Southern woman in the second half of the 19th century came up with peanut brittle by accidentally putting baking soda into her taffy instead of cream of tartar.

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 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.

If your peanut brittle is not hardening, it's because the sugar mixture did not get hot enough to properly caramelize, cool and become hard, crisp and crunchy. If you have this issue, next time, use a thermometer to make sure the peanut brittle mixture gets to 300°F.

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.

But did you know that this popular treat may very well be an American invention? That's right. And an American folk hero of yore may have helped garner its fame. In fact, peanut brittle's place in American pop culture is certainly an established one.

Peanut brittle's prominence during holidays and celebrations solidified its place in American culinary traditions. The southern United States, known for its love affair with pecans, introduced another star to the brittle scene: pecan 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.

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

Can peanut brittle go bad? ›

In cool, dark, and dry conditions, peanut brittle will last for an extremely long time. If kept vacuum sealed, it would last even longer. Your two biggest spoilage factors for peanut brittle would be moisture and rancidity.

As the sugar is cooking and begins turning amber in color it accumulates small amounts of acid, and that acid reacts chemically with the alkaline baking soda releasing about a zillion minuscule bubbles of CO₂ that get trapped, making the sugar porous and, well… brittle.

As mentioned in “how to make peanut brittle”, it's very important to move fast after the peanuts and baking soda are mixed in. If not, the peanut brittle will turn out too thick and clumpy. Don't play the guessing game and use a candy thermometer instead. This will ensure your peanut brittle turns out perfectly golden.

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.

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!
