Batidas (pronounced ba-chi-da) is Portuguese for "shaken" or "milkshake." The drinks are cachaca cocktails made with fruit juice or pureed fruit, usually with sugar added. Milk or sweetened condensed milk are also common ingredients.
Batidas are thicker, very sweet drinks that take full advantage of the sugarcane flavor of cachaca, although vodka can be substituted if cachaca is unavailable. They need to be shaken vigorously or made in a blender, and are traditionally served in very small glasses.
