Cape Gooseberry Jam is a traditional African Fusion recipe for making a fruit jam (jelly) from the physalis fruit, which is also know as the Cape gooseberry. The full recipe is presented here and I hope you enjoy this classic African Fusion version of: Cape Gooseberry Jam.
Wash the Cape gooseberries then remove and discard any stems and the outer, papery covering of the fruit before quartering. Place in a pan along with the water then bring to a boil, reduce to a simmer and cook for 30 minutes, mashing the fruit against the side of the pan with a wooden spoon until the fruit is tender. Take off the heat and mash the remainder of the fruit with a potato masher.
Add the sugar to the saucepan, heat through, stirring until completely dissolved then add the butter. Bring to a boil and cook rapidly for about 15 minutes. Test for setting by placing a plate in the fridge. Spoon a little of the jam onto the plate, allow to cook then move it with your fingernail. If a crinkly skin forms then the jam is ready. If not continue boiling for 5 minutes more and test again.
Skim the surface then ladle into sterilized jars that have been warmed in an oven set to 100°C for 5 minutes. Allow 1cm of head space then secure the lid, allow to cool and store.
