Peanut brittle is a sweet, old-fashioned treat that can be challenging to make. The process involves cooking sugar, corn syrup, water, and salt in a saucepan until the sugar dissolves and the mixture boils. Stirring in peanuts and baking soda, and pouring the mixture onto a prepared baking sheet to cool and harden are the next steps. However, removing the hardened peanut brittle from the pan can be tricky, as it tends to stick. Greasing the pan generously with butter or margarine before pouring in the mixture is essential to prevent sticking. Additionally, ensuring the mixture reaches the correct temperature of 300°F to 310°F is critical, as undercooking or overcooking can result in a sticky or chewy texture.

What You'll Learn
Use a candy thermometer to check the temperature
A candy thermometer is an essential tool when making peanut brittle, as it ensures the candy reaches the right temperature and thus its desired consistency and texture. The difference between a chewy and a brittle candy can be just a few degrees, so accuracy and precision are vital.
When choosing a candy thermometer, you can opt for a traditional glass tube thermometer or a digital one that beeps when the desired temperature is reached. Digital probe-style thermometers, such as the Thermapen by Thermoworks, are extremely versatile and can be used for both candy and meat. They are also very accurate and can take a measurement in less than one second. If you want to try your hand at candy-making without breaking the bank, an inexpensive candy/deep-fry thermometer like the Taylor candy thermometer, priced under $15, will work well for most candy-making needs.
Before using a candy thermometer, it is important to calibrate it to ensure accurate readings. To do this, simply clip the thermometer to the side of a pan, making sure the bulb isn't in contact with the bottom, and add water. Bring the water to a full boil and check that the thermometer reads 212ºF or 100ºC. If it doesn't, it's time to get a new thermometer or adjust your readings accordingly.
When using a candy thermometer, safety is paramount as boiling sugar syrup is extremely hot and can cause serious burns. Always follow your specific candy recipe's instructions, but here are some general tips for success:
- Keep a bowl of ice water nearby in case of accidental burns.
- Be careful when handling the thermometer and consider using oven mitts for extra protection.
- Avoid drastic temperature changes if using a glass thermometer to prevent the glass from breaking.
- Keep an eye on the thermometer as temperatures can rise swiftly, especially as you approach your target.
- Make sure the thermometer bulb isn't touching the bottom of the pot to avoid inaccurate readings.
- The temperature will continue to rise for a short while even after removing the pot from the heat, so keep this in mind when targeting a specific temperature.

Grease the pan with butter or margarine
Greasing a pan with butter or margarine is a great way to prevent your peanut brittle from sticking. Here is a step-by-step guide:
Firstly, take a stick of butter or margarine and rub it all over the inside of the pan, ensuring that you cover the bottom and sides evenly. You can also use a paper towel to wipe the butter or margarine onto the pan if you prefer. This will create a non-stick surface, making it easier to remove your peanut brittle later.
Next, add a couple of tablespoons of all-purpose flour into the greased pan. Rotate and tap the pan until the flour covers every greased surface. Then, discard any remaining flour. This step will help create an even more effective non-stick barrier.
If you are making a layer cake, you can also cut a piece of parchment paper to fit the bottom of the pan. Place the parchment paper in the pan after greasing it, but before adding the flour. Grease the parchment paper, then add the flour as usual. This extra step will ensure that your peanut brittle comes out of the pan with ease.
If you don't have butter or margarine, there are a few alternative options you can consider. Vegetable oil can be used as a substitute, and it is actually what is in commercial non-stick spray oils. Simply use a paper towel to wipe the oil onto the pan, just as you would with butter or margarine. Alternatively, you can line your pan with parchment paper or a silicone baking mat, which will also help prevent sticking.

Avoid using wax paper
When making peanut brittle, it is important to avoid using wax paper. Wax paper will melt and stick to the peanut brittle, leaving unsightly streaks and an inedible product. Instead, you can use parchment paper or a silicone baking mat. You can also butter a baking sheet or use a silicone spoon to spread the mixture.
It is also important to note that timing is crucial when making peanut brittle. All ingredients and equipment should be ready to go before starting, as the process happens quickly and requires immediate reactions. The temperature must also be precise, as even a slight variation can affect the outcome.
Additionally, it is recommended to use a bigger saucepan, at least triple the volume of the ingredients. This is because the boiling syrup increases in volume and needs ample room for expansion.

Use parchment paper or a silicone mat
Using parchment paper or a silicone mat is a great alternative to greasing your pan. However, it is important to note that wax paper is not a suitable alternative as it will melt and stick to the peanut brittle.
Parchment paper is paper that is coated in a layer of silicone to create a heat-resistant and non-stick surface. It is disposable and can be tailored to fit any pan by cutting it with scissors. However, it is usually single-use and creates more waste.
On the other hand, silicone mats are reusable and can withstand higher temperatures. They are also easier to clean than parchment paper, as they do not require scrubbing to remove hard-set residue. However, they should not be used with a knife as this will damage the surface, making it more difficult to clean.
When deciding between parchment paper and a silicone mat, consider the task at hand. Parchment paper is better suited for lining cake pans, baking cookies, and catching drips from glazing or icing cakes. Silicone mats, on the other hand, are ideal for working with hot confections such as caramel or toffee, as well as for cooking savoury foods like salmon or chicken breasts.
For making peanut brittle, a silicone mat is the better choice as it can withstand the high temperatures and sticky nature of the candy. However, if you don't have a silicone mat, parchment paper can also be used successfully. Just be sure to spray it with non-stick cooking spray first to ensure the peanut brittle doesn't stick.

Reheat and repeat the final cooking steps
If your peanut brittle has turned out too soft or chewy, you can reheat and repeat the final cooking steps to rescue it.
First, test your thermometer in a saucepan of boiling water for a few minutes. It should read 212ºF (100ºC). If not, calibrate accordingly so you know what the “true” 300ºF is on your thermometer.
Next, break up the peanut brittle and place it in a glass, microwave-safe bowl. Heat on high for 1-2 minutes until soft and semi-melted. Melting it in the microwave first prevents it from burning in the pan before it liquifies and can be stirred.
Now, transfer the semi-melted brittle to a clean saucepan. Continue heating and stirring over medium heat until it reaches the adjusted 300ºF temperature.
Finally, immediately remove the pan from the heat and add an extra 1/2 teaspoon of baking soda. Pour the mixture onto a prepared baking sheet and let it cool.

Frequently asked questions
Your peanut brittle may be stuck to the pan because it was undercooked, or not heated to 300°F (149°C). Undercooked peanut brittle is often sticky and doesn't set properly.
To prevent peanut brittle from sticking to the pan, grease the pan generously with butter or margarine. You can also line the pan with parchment paper or a silicone baking mat.
If your peanut brittle is stuck to the pan, try passing the pan over an open flame to soften it slightly, or use a mallet to break it into pieces.
A candy thermometer is important for making peanut brittle because it allows you to monitor the temperature accurately and ensure that the mixture reaches the hard-crack stage (300°F/149°C). This helps to prevent undercooking or overcooking the brittle.
If you don't use a candy thermometer, you can do a water test by dropping a small amount of the boiling syrup into a bowl of cold water. If it forms hard, brittle threads, it's ready.
