A delicious preserves recipe made from ground cherries (Physalis pruinosa).
After one hour, prepare/sanitize your canning jars in a pot of boiling water - if you're not using a pressure canner.
Mix in pectin. Bring the pot to a rolling boil stirring constantly to prevent sticking. Then add the sugar, bring to boil again for about 1 minute. Reduce or remove from heat after the preserves reach boil, continuing to stir to prevent sticking. Use a cold spoon from your freezer to spoon test the preserves to make sure they're as thick as you want them. If not, continue to cook and use the spoon test every 5 minutes or so until desired consistency has been achieved.
Just before canning, mix in brandy and vanilla. Both of these ingredients contain volatile flavors that will dissipate with prolonged heat exposure, so adding them just before canning maximizes their flavor preservation.
Fill sanitized jars with ground cherry preserves, and boil them for at least 15 minutes. Jar lids should make a "pop" sound and seal soon after removing from boiling water bath. Cool your ground cherry preserves and store them! *Yield will vary depending on how much water you cook off of your preserves.
