White sapote (lat. Casimiroa edulis) is an evergreen tree that’s native from southeastern Mexico south to Costa Rica. The tree produces smooth-skinned fruit with a soft pulp and white seeds. Depending on the variety, the flavor can range from bland or bitter to sweet.
When ripe, the fruits of selected varieties have a sweet pulp with a texture that’s reminiscent of avocados. The fruits are usually eaten out of hand, but they can also be made into ice cream, milkshakes, desserts, and marmalades. Interestingly enough, the poisonous seeds contain glycosides, which have been used in medicine as a sedative.
