Cook currants until soft, adding the water to prevent them from sticking. Once cooked, press currants through a sieve or food mill.
Combine the currant pulp and crushed raspberries in a large pot. Add sugar, stirring until dissolved. Cook rapidly until it reaches your gelling point. Stir often to prevent sticking!
Remove from heat. Skim foam if needed.
Lade hot jam into hot jar, leaving ¼” headspace. Wipe the rims clean and place your lids and screw bands.
Place jar in the canner and process.
Processing with Water Bath Canner
After all jars are in the canner, lower rack into the water. Bring to a boil.
When the water comes to a rolling boil, start your time.
Processing Time
Process half-pints or pints for 15 minutes. Be sure and adjust your time for altitude:
0-1,000 ft - 15 minutes 1,001-3,000 ft – 20 minutes 3,001-6,000 ft – 25 minutes 6,001-8,000 ft – 30 minutes 8,001-10,000 ft – 35 minutes
Process for the full time indicated, adjusting the heat as needed to maintain a boil for the entire processing time.
Cool Down Time
When processing time is completed turn off the heat.
Remove the canner lid and wait 5 minutes.
Remove your jars. (optionally you can wait another 5 minutes if the contents appear to be bubbling so hard it is coming out of the jars)
Put the jars a few inches apart on a thick towel and allow them to cool to room temperature undisturbed. 12 hours is suggested.
When the jars are cooled, remove the metal bands, check the seals, wash jars, dry completely, and store in a cool dark place.
Enjoy!
Notes
Process half-pints or pints for 15 minutes. Be sure and adjust your time for altitude:0-1,000 ft - 15 minutes 1,001-3,000 ft – 20 minutes 3,001-6,000 ft – 25 minutes 6,001-8,000 ft – 30 minutes 8,001-10,000 ft – 35 minutesIf you want to can in half pints that is fine. Just process for the same time as pints. Do not can this in quart jars. You can also just put this in jars and in the fridge if you want to skip the processing step.
