Mexican wedding cookies
A Russian tea cake, Mexican wedding cookies or snowball cookies is a kind of pastry, often eaten around Christmas time in the United States. Russian tea cakes have a relatively simple recipe, generally consisting entirely of flour, water, butter, and ground nuts, the nut variety depending upon the cookie type. After baking, they are rolled in powdered sugar while still hot, then coated again once the cookie has cooled. European recipes rely upon coarsely chopped hazelnuts, almonds, or walnuts. Mexican wedding cookies, also known as "Polvorones", are rich, buttery, nutty cookies with a crumbly texture that melts in your mouth. While they share similar ingredients with Russian tea cakes, they traditionally use coarsely chopped pecans or almonds. A hint of cinnamon is often added, providing a subtle warmth and enhancing their rich, nutty flavor.
