Almendrados are traditional Spanish cookies. They're made with a combination of blanched almonds, granulated sugar, eggs, and lemon zest. Egg whites are first beaten until stiff, then combined with sugar, egg yolks, lemon zest, and ground almonds.
The combination is spiced with cinnamon, if desired, and it's then shaped into mounds or pyramids and baked until golden. Dating back to the 15th century or before, almendrados are often made during the festive Christmas period as a tasty dessert or snack.
