In parts of theMiddle East, brittle is made withpistachios,[10] while many Asian countries usesesame seeds and peanuts.[11] Peanut brittle is the most popular brittle recipe in theUnited States.[12] The term "brittle" in the context of the food first appeared in print in 1892, though the candy itself has been around for much longer.[13]
Traditionally, a mixture of sugar and water is heated to thehard crack stage, reaching approximately 146 to 154 °C (295 to 309 °F). Some recipes may call for ingredients such as glucose and salt in this step.[14] Next, nuts are mixed with thecaramelized sugar. At this point spices,leavening agents, and oftenpeanut butter or butter are added. The hot candy is then poured onto a flat surface to cool, typically a granite slab, a marble slab, or a baking sheet. The hot candy may be troweled to uniform thickness. When the brittle is cool enough to handle, it is broken into pieces.[15] It is also rare to break the brittle into equal pieces.
