The now popular tomatillo can no longer be considered an exotic vegetable. It has become common in home Gardens in the Denver metro area according to Colorado State University Cooperative Extension Master Gardeners. Tomatillos can be safely canned just as are tomatoes. Varieties of tomatillos have names such as Husk Tomato, Ground Cherry and Chinese Lantern Plant. They vary in color from vivid yellow or greenish orange and even purple, depending on the variety.
Tomatillos look like small tomatoes with a paper husk.
Select those that are firm to the touch and smooth without any bruises or shriveling. Some say they taste somewhat like a green apple or a green tomato. They have a mellow piquant flavor when cooked. This makes them an ideal ingredient in salsas. They can be substituted in any canning recipe that calls for tomatoes, although there will be a flavor difference.
