Take one pound of kumquats. Pick them over to make sure that you don’t have any that are turning to mush. Cut off the stem end and slice the kumquat into quarters.
When all the kumquats are quartered, use a knife to scrape away the inner membrane and any seeds. This will leave you with a small piece of rind with some pulp still attached. Once all kumquats are quartered and seeded, chop them into thin ribbons. You should yield about two cups of chopped kumquat bits.
Take 1-2 jalapenos, depending on how spicy you like your jam, and mince into small pieces. If you like heat, feel free to keep the seeds.
Place the chopped kumquat and jalapeno in a large pot with 2 cups water and 1 1/2 cups sugar.
Bring to a boil and cook for 15-25 minutes, until it reaches 220°F. Pour in liquid pectin and continue to cook for about a minute.
Once it has reached temperature and thickened, remove jam from heat. Funnel into two prepared half pint jars. Wipe rims, apply lids and rings and process in a small batch canning pot for 10 minutes.
Notes
One great way I test my jams is to drop a small spoonful of jam on a plate I’ve put in the freezer for about 5 minutes. If the jam sets up on the plate, it is ready to be canned and has reached proper temperature.
