Cherimoya

Your fruit puzzle today is a custard apple, perhaps known more popularly as a Cherimoya

After eating it, I thought about putting the hard, black seeds out for the squirrels, but decided against.

Then I read this in Wikipedia:
“The flesh of the cherimoya contains numerous hard, inedible, black, bean-like, glossy seeds, 1–2 cm (0.39–0.79 in) long and about half as wide. Cherimoya seeds are poisonous if crushed open. Like other members of the family Annonaceae, the entire plant contains small amounts of neurotoxic acetogenins, such as annonacin, which appear to be linked to atypical parkinsonism in Guadeloupe. Moreover, an extract of the bark can induce paralysis if injected.”

Good thing I don’t read up on all my treats before eating them.
