French macarons originated in Italy in the 17th century based on recipes for almond biscuits, but did not become the sandwich cookies known today until the 1830s. Traditionally filled with ganache, buttercream, or jam, macarons come in many flavors from almond to chocolate to more unusual combinations like peanut butter and jelly. While specialty tools can help, macarons can easily be made at home with just a few ingredients like almond flour, powdered sugar, egg whites, and granulated sugar. The basic method involves whipping egg whites, folding in the dry ingredients to form a thick batter, piping rounds onto a baking sheet, and baking for 10-12 minutes until set.
