The Frozen Custard Apple aka The Fresh-Frozen Cherimoya!
You will find them in the frozen section, three or four in a plastic mesh bag. I have no clue how to pick out a "good" bag. Just pick one that looks good to you.
Let it defrost fully. It will develop a frost fuzz, which makes it totally look like a little frozen brain.
Of course I could not wait for it to fully defrost. I broke it open as soon as I could.
It wasn't too bad. Not like the passionfruit incident. The taste is sort of frozen-flabby-sweet-beige and so I really need to try letting one defrost completely before eating it.
When and if that should happen, you will be the first to know.
