You guys are good!
I think you had fun with this one!
Hats off to all the participants for their creative suggestions on this one. I tried very hard to be tricky.
Susan V. was correct - this is a half over-ripe bitter melon! It was originally all green, but over the last two days it is rapidly turning a lovely bright orange.
What's a bitter melon? A bitter tasting vegetable used in Asian cooking. I purchased it at our local farmers market, where the seller suggested stir-frying it in butter. It is considered a medicinal food, particularly for those with diabetes, but also cancer and other infections.
