Atis is made up of raisin-sized seeds, each covered with sugary sweet and delicious pulp. You take the pulp, which is similar in fibrous texture to the guyabano, and spit out the seeds. It needs quite a bit of tongue-and-tooth coordination work to get the delightful pulp, and you have to be careful not to accidentally swallow the seeds. The fruit itself contains lots of vitamins and minerals, among them Vitamin C or Ascorbic Acid, Phosphorus, Calcium, Iron, Niacin, Riboflavin, Thiamine and Carotene.
