Star Apple

Chrysophyllum cainito is a tropical tree of the family Sapotaceae, native to the lowlands of Central America and the West Indies. It grows rapidly and reaches 20 m in height.
It has round, purple-skinned fruit that is often green around the calyx, with a star pattern in the pulp. Sometimes there is a greenish-white or yellow variety of the fruit. The skin is rich in latex, and both it and the rind are not edible. The flattened seeds are light brown and hard. It bears fruit year around after it reaches about seven years of age.

In the Philippines we call the fruit of the Chrysophyllum cainito "caimito" or "star apple" in English. And it seems that it's caimito season again. One street I pass through almost everyday have vendors, lined up along the sidewalk, with baskets of caimito for sale. The vendors started selling them only around a few weeks ago. I asked my mom to buy some when she gets the chance.
