Mangosteen are delicious and VERY DELICATE. I’ve only noticed them being sold at AJ’s Fine Foods and the Asian Market. It’s hard to describe the flavor but it’s very tropical tasting not the same but almost like passion fruit and lychee mixed together in ultra soft delicate tangerine like segments.
What nobody tells you is that they are dangerous to open. I read that when they are fresh and just picked they are easier to open. The mangosteen we get here have a thick shell that’s like is like hard waxy wood and gets harder every day. Mangosteen requires much more skill with a knife than hard squash.
