Ground Cherry and Watermelon Salad

They don’t grow in the ground, like potatoes, and they’re not stone fruit, like cherries, so why the deceptive name? They also share more semblance in taste to citrus rather than cherry or grape tomatoes, whose appearance they’re strikingly similar to, at least once their tomatillo-like husks are stripped. Which might leave one to throw their hands up and exclaim, what is this fruit/vegetable/freaky plant? At least it doesn’t have a stray animal in its name, gooseberry.
