Acai is a 1-inch round berry that comes from the acai palm tree, which is native to the rainforests of Central and South America. While it is usually referred to as a berry, Acai is actually a drupe, which is a seed with three layers: the outer layer, the fleshy layer, and the hard shell layer encasing a seed. Acai berries are grown in Central and South America and are prepared by puréeing the fruit into a smoothie in a bowl or glass, topped with fruit, nuts, seeds, or granola. Acai bowls are typically topped with granola, banana, and guaraná syrup in Brazil, but several other variations can be found throughout the country, including acai bowls topped with tapioca balls and a saltier version that is topped with shrimp or dried fish. Acai is also used in smoothies, juices, and other recipes. Acai berries are high in antioxidants, fiber, and vitamins and minerals, such as vitamin C, manganese, and potassium.
