I've never known how to cook a tomatillo jam until I grew a shrublike plant with yellow flowers and thick-husked fruits. They are more often called
ground cherries. Lots of gardeners in Texas (of various zones) dote on the tomatillo because these edible flower-fruits reseed like hell they don't have difficult time planting them. Another is that these tomatillos have been good sources of Vitamin C like any citrus fruit. So far, I've collected recipes which allows me to include the tomatillo in the meal.
