This time last year, I began harvesting piles of ground cherries (also known as cape gooseberries, Physalis ‘Cossack Pineapple’). The tiny fruits grow in a husk, like the tomatillos to which they are related. When the husk turns dry and brittle and the fruits are golden without a hint of green, they’re ripe and ready to eat. They’ll often fall off the bush when they’re ready, which is why they’re called “ground cherries.”
The plants grew exponentially in the hot weather and set fruit faster than I could pick it. But, having never grown nor eaten them before–I do love an experiment–I didn’t know what to do with them. I can certainly recommend eating them like popcorn. They’re exceptionally high in vitamin C and make a terrific snack.
Craving variety from eating them out-of-hand, I began experimenting with canning. Appalled by the amounts of sugar most recipes directed me to add, I turned to Pomona’s Universal Pectin, which permits the cook to cut the amount of sugar in the recipe by about half.
I began, logically, with Pomona’s recipe for Ground Cherry Jam but wanted to give it some flair. Taking a cue from recipes I’ve seen combining stone fruits and rich spices (cinnamon plum, vanilla peach, etc.), and inspired by another combination I saw online once but can no longer find, I split open a bag of chai tea (yes, redundant) and dumped the leaves into the pot in Step 5 of Pomona’s recipe, when the fruit is brought to a boil (I added the tea, then the pectin mixture). The leaves and spices were finely ground, but you may break the bag into a ramekin and sift out larger pieces before adding it to the jam, if you wish.
I stirred it well, then proceeded to fill the jars and boil as directed.
It is absolutely delicious; a lovely combination of bright citrus and smoky spice.
