My father used to eat these growing up in Tanganyika, now Tanzania, he called them in the local language, songwa. These were labelled physalis when I bought them, though I have heard them more commonly called Chinese gooseberries, sometimes Cape Gooseberries. These come from Colombia. They do not tasted like gooseberries, rather have a slightly sour-sweet citrus flavour, very refreshing and unusual. They are quite expensive, a small container, which contains about 20 of them, costs about $4. Quite different than what my father remembers, there were so many, they could make jam of them.
