Canistel - Pouteria campechiana

Imagine a fruit that has a dry custard-like texture and tastes like egg yolk. That is the canistel, a.k.a. Egg Fruit. Quite different that its relatives - sapodilla, and mamey sapote...
As you can see in the photo below, canistel should be harvested when fruit turn yellow-orange.

http://edis.ifas.ufl.edu/HS299 suggests allowing fruit 3 to 10 days to ripen at room temperature until soft but not mushy. Once fruit is ripe it may be stored in the refrigerator for several days prior to use.

I do not know the variety I have, although they seem to have or 1 or 2 glossy brown seeds per fruit, as seen above.
