Tropical Carambola fruit is widely known as starfruit and makes a great Carambola and Strawberry Jam. If you live in the south or have a carambola tree dropping fruit all over the place make jam with the ripened carambolas. Homemade carambola jam is a delicious tropical jam with an unique flavor.
Wash and remove any blemishes from the carambola fruit.
Slice them and the remove all seeds before putting the fruit in the pot.
Wash hull and slice strawberries.
Add the sugar into the large pot with the fruit and place on the stove on a medium heat.
Stir the fruit and sugar with a wooden spoon to get the fruit juices flowing.
Add the lemon juice and butter or margarine to the pot. The butter or margarine will help cut down on foam.
Stir the sugar and fruit occasionally.
Allow the sugar to melt completely on the medium heat. You don’t want the sugar crystals to burn from too high a heat at this point.
Once the sugar has melted turn the heat up to medium-high, carefully stirring occasionally and bring to a rolling boil.
Add the liquid pectin and bring to a rolling boil once again.
Cook fruit mixture for one full minute using a timer.
Immediately once the minute is up remove the pot from the heat to your countertop. Wait until the mixture settles down and skim the foam from the top with a large spoon.
Using a ladle and a wide mouth funnel fill your jars leaving ¼ of headspace.
Wipe the rims of the canning jars with a damp paper towel and put the flat lid on.
Screw your lid bands on.
Continue filling all your jars and process in a boil water bath for 10 minutes.
