Tomatillos are the the green cousin of the tomato that grows inside a papery-husk and is the main ingredient in salsa verde. They can also be used in stews, curries, meat dishes and soups. Tomatillos are rich in minerals and a fairly good source of vitamins A and C.
Ground cherries are...well, you just have to taste them! They're like nature's little pre-packaged treat and one of our (North American) native fruits. Since they fall to the ground when ripe, ground cherries make for great "treasure hunts" for kids. They're easy to grow, hardy and pest-resistant (as far as we know!) - treat them as you would tomatoes but no staking required.
