For perfectly beautiful brittle, follow our step-by-step guide including how to caramelize sugar for a nutty, rich taste. Peanut brittle is the most classic brittle recipe, but we encourage you to shake things up and try a different nut variety. Almonds are delicately sweet on their own. Pistachios would make a great option, too. Once you master the brittle technique, you can get creative with the ingredients you use and customize your very own brittle recipe.
