About a month ago, I became obsessed with ground cherries, members of the nightshade family. Looking like tiny golden cherry tomatoes wrapped in the papery husks of tomatillos, these tasty little bites have a flavor profile reminiscent of pineapple and other tropical fruits. Ground cherries are a good source of Vitamins A and C, and a cup contains only about 75 calories. Some people turn them into pie or jam. I prefer just to turn them inside out and pop them in my mouth.
