Recipes for homemade peanut brittle are available on Epicurious.com, FoodNetwork.com, MyRecipes.com, BettyCrocker.com and LandOLakes.com. Aside from peanuts, the main ingredients for making peanut brittle typically include sugar, corn syrup, butter, water and baking soda. Many recipes also use vanilla extract to add extra flavor.
To make peanut brittle at home, use a saucepan to cook the ingredients before pouring the mixture into buttered baking sheets and allowing it to cool. A candy thermometer comes in handy during the cooking process as it ensures that the mixture reaches the correct temperature for desirable results. When the peanut brittle is cold and hard, break it into pieces and store the candy in an airtight container.
