Ground cherries/husk tomatoes

Is anyone familiar with these? Betsy just came home from farmers' market with some. About size of a small grape, in a husk like a tomatillo. Flavor is .....different. Like a gooseberry meets a sweet tomato. Couple questions for anyone familiar:
1)Does anyone know how long this can be kept? Any idea if refrigeration is a no-no (I hate tomatoes that have been refrigerated)?
2) Was thinking of serving with good ripe heirlooms in a salad, any other idea?

This is one of the Physalis genus, a very close relative to the Cape gooseberry (which I used to see in the grocery store in the UK sometimes) and, as you observed, not very far removed from the tomatillo. I think you could use these fresh in salads or make jam or jelly out of them. Being closely related to tomatillos and not all that far from tomatoes, I'm guessing you're safer not refrigerating. In the grocery store, I recall the Cape gooseberries being in the slightly-cool section.

Dale, do you think you could marry these with jalapeño, garlic, and onions, and make a decent salsa verde? They sound like they would work well. Although, one could just as easily use real tomatillos huh?

Bob,
these are sweeter/fruitier than tomatillos, and I'd rather do something a little more distinctive.
Mark,
thanks for info!

Dale,
I just consulted with NJ, who being raised on a farm, is somewhat familiar with ground cherries. She said, her family would make them into pies, preserves and the best part was just popping them in your mouth.
Not very distinctive, but that's her story and she's sticking to it.
