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.

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.

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.

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.

Grittiness can happen when a stray sugar crystal doesn't melt properly or is introduced while the caramel is cooking. The stray crystal causes the surrounding sugar to crystallize, resulting in that gritty texture once the caramel has cooled.

You'll also want to prepare a baking sheet, with either a silicone mat or parchment paper. The mat/paper will help ensure the peanut brittle doesn't stick directly to pan once it has cooled.

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.

The secret is in the baking soda. 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.

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.

Can you make peanut brittle in humid weather? ›

Because excessive softness in candy results from high relative humidity, cook hard candies, such as nut brittle, to 2 degrees higher than the temperature your recipe calls for. The additional 2 degrees in cooking temperature will compensate for moisture in the air, so your candy will still have the correct texture.

In a medium pot over medium-high heat add sugar, corn syrup and peanut; stirring constantly until peanuts start to turn light brown and smell cooked - approximately 8 - 10 minutes. The batter will be clumpy and will turn into a bit of a ball before it starts melting. Remove from heat.

Pour onto prepared pan and spread to form a single layer of peanuts. Cool completely, then break into pieces. It is important not to stir this mixture after it has dissolved. This will cause the mixture to crystallize and will result in a gritty, cloudy product.

Pralines have a lot in common with nut brittle, with the difference being mostly in the addition of cream and the cooking temperature––the sugary syrup used to coat pralines is heated to a soft-ball consistency, a lower temperature than the hard-crack stage of peanut brittle.

When the baking soda combines with the boiled sugar, it creates Carbon Dioxide that form lots of bubbles and puff the candy up. Once it hardens, the bubbles get trapped inside and create a texture that looks just like a sponge or piece of foam.

Why do you put baking soda in peanut brittle? In short: the alkaline of the baking soda reacts with the acids of the sugar to creates lots of CO2 bubbles. This interrupts the crystalline structure, making it more delicate and easily cracked…and thus more “brittle”.

Examples of interfering agents include corn syrup and cream of tartar. A key step in making brittle is heating the syrup to the proper temperature.

In summary, the purpose of adding baking soda to dough is to generate carbon dioxide gas, which causes the dough to rise and become light and fluffy. This is important because it makes the dough easier to work with and results in a better texture and flavor in the final baked product.
