This traditional Mexican winter drink is basically made from corn dough or masa, and water or milk for a richer taste, seasoned with ground cinnamon and other spices like chili, for example. Over hundreds and thousands of years, locals have elaborated plenty of varieties of this nice dish—depending on the region, you might come across chocolate flavour, blackberry, pineapple, and other fruit tastes, as well nut flavours—particularly pecan and peanut.
Atole could be thick or thin, sweet or not really. It's commonly served for breakfast, or eaten as a warming up snack. It is one of the specialities during the Day of the Dead and Christmas celebrations.
