Macarons are French meringue-based sandwich cookies with a crispy shell and chewy center. They are made with egg whites, almond flour, sugar, and sometimes food dye, and sandwiched together with fillings like buttercream, ganache, or jam. Macarons are known for their melt-in-your-mouth quality and they are available in 22 different flavors, including 5 seasonal flavors that change every 3 months.
