Identify this unusual spicy appetizer A friend of mine years back related a story about an appetizer that he ordered at an Asian restaurant that was apparently quite unusual. It was a bowl of something (possibly peppers or another vegetable) where each piece looked completely identical, but one out of every 15-20 of them was extremely spicy. The rest tasted rather mild, so he and his friends would go around the table basically playing a kind of Russian roulette with spicy food.

Does anybody have any idea of what this could be?
It sounds like it could be Shishito peppers, which about 10% are spicy, and "even experts may not be able to distinguish relative hotness on the same plant.".
