s. The freshness and greenness of the husk are quality criteria. Fruit should be firm and bright green, as the green color and tart flavor are the main culinary contributions of the fruit. Purple and red-ripening cultivars often have a slight sweetness, unlike the green- and yellow-ripening cultivars, and are therefore somewhat more suitable for fruit-like uses like jams and preserves. Like their close relatives cape gooseberries, tomatillos have a high pectin content. Another characteristic is they tend to have a varying degree of a sappy sticky coating, mostly when used on the green side out of the husk.
Tomatillo plants are highly self-incompatible
(two or more plants are needed for proper pollination
; thus isolated tomatillo plants rarely set fruit).
Ripe tomatillos will keep in the refrigerator for about two weeks. They will keep even longer if the husks are removed and the fruits are placed in sealed plastic bags stored in the refrigerator. They may also be frozen whole or sliced.
