Tomatillos are the odd-looking distant cousins of the tomato. Native to central America, they can be found growing wild in fields of corn and beans, and they are gathered to be eaten or sold in local markets. The name and the requirements for growing tomatoes and tomatillos are similar, but the comparison really stops there. The appearance of a tomatillo (pronounced to-ma-TEE-yo) with its papery husk is quite different. In fact, it is also known as a husk tomato, due to the dry cover that surrounds the fruit. Tomatillo plants are highly self-incompatible, and two or more plants are needed for proper pollination. Thus, isolated tomatillo plants rarely set fruit.
