Groundcherries are a native plant in the Physalis family which is often overlooked as a forage food. They make those cute little Chinese lanterns which are sometimes sprayed orange and sold by florists at Halloween. They actually look like tomatillos as well. The plant is about 2 feet tall and the leaves are dull green, oval and pointed. Find ripe fruit by squeezing the lanterns. The best ones to squeeze may look a bit faded. When you find a small marble pick it and pop off the jacket. It will be sort of olive green. Taste it. It should be sweet tart. They can be dried, eaten fresh, or made into jam.
To be honest, I have been growing a more abundant and delicious version from seeds I was given by our Peruvian friend Leon in Yarinacocha. He told me that the husks could be made into a tea which is a treatment for the cough which accompanies congestive heart failure. It is also known to Guatemalan friends as Tomate de Sope, and is a favorite of children in South America. The Peruvian ones are sold dried as Inkaberries for an exorbitant sum in our local health food store. They make a lovely snack for hiking as they are so mall and concentrated. I find them hard to dry without a dehydrator because they have a slightly resinous surface, but to me they taste like extra-sweet yellow raisins. The silver lining to that is that the Peruvian ones fall on the ground, rather than persisting as the North American ones do, but you can still collect them because they are in a little wrapping and they take a long time to rot. They create a carpet of fruit, and I gather buckets, then sit and husk them when I have to sit somewhere for a while.
I throw them in the blender, then make jam using any ground cherry jam recipe on the internet. It needs pectin, and I have sometimes added a grate of lemon peel, but it has a sort of mild, luscious tropical flavor and a nice golden color. Very seedy, but the seeds are tiny. They have become a weed in my garden, but a delicious one. I ended up cutting them all down to start the fall garden, but I will hang a bunch upside down in the shed for winter snacks.
The Jam Recipe, (and how to do all that stuff)
The jam is so yummy- a bit like yellow plum jam but a hint of something tropical. I grated a bit of lemon peel into it. Here’s how I did it.
4 cups husked fruit
3 c. sugar
3 tbsp pectin
1/2 tsp grated lemon or lime peel, organic if available, or just scrub really well and offer a quick blessing…
1/4 cup lemon juice
Throw the fruit in the food processor and chop. Dump in pot, stir in pectin and lemon, bring to a rolling boil for one minute, add sugar, bring back to boil 1 minute, check for sheeting, pour into sterilized jars and cap when sheets.
“Sheeting?” OK, for those to whom all this jam making stuff is new, go to Jams and Jellies. Don’t be scared. You need to know this.
