Physalis de John Spottiswood

Like its relative the tomatillo, the Cape gooseberry is covered with a papery husk. The fruit inside looks a bit like a yellow cherry, and tastes like a sweet tomato. You can eat Cape gooseberries whole, minus the husk, or use them to make very tasty preserves. They're hard to find in the United States; your best bet is a specialty produce market in the spring.
