Custard apples (a.k.a. Budda-head fruit) 釋迦

This is a custard apple, also known as the Budda-head fruit (釋迦 shì jiā). It's a soft fruit (much like custard) that is grown a lot on the east coast (near Taitung in the southeast). They typically cost 50NT per fruit or less and there's a couple of varieties, including "original" and the pineapple custard apple, which is a sturdier version of the fruit. Look for them in the wintertime at the markets (and perhaps other times of the year, too, if you're closer to the east coast). To eat it, I cut it in half and dig out the white fruit with a spoon, spitting out the seeds. Try it!
