A simple three-ingredient preserve featuring ripe blackcurrants, sugar, and fresh lemon juice. Ready in under an hour with no special equipment needed.
# Preparation Steps:
01 - Place a small plate in the freezer to use for jam set testing.
02 - In a large heavy-bottomed saucepan, combine blackcurrants and lemon juice. Gently crush some berries with a potato masher to release juices.
03 - Add sugar and stir to combine. Let sit for 10 minutes to draw out juices from the fruit.
04 - Place the saucepan over medium heat. Stir until sugar dissolves completely.
05 - Increase heat to high and bring the mixture to a rapid boil. Stir frequently to prevent sticking.
06 - Boil hard for 10 to 15 minutes, skimming off any foam. To test setting point, place a drop of jam on the chilled plate. Wait 1 minute, then push gently with your finger—if it wrinkles, the jam has reached the correct consistency.
07 - Remove from heat. Let sit for 5 minutes, stirring occasionally to distribute fruit evenly throughout the jam.
08 - Ladle hot jam into sterilized jars, leaving 0.25 inch headspace. Seal immediately with lids.
09 - Let cool at room temperature, then label and store in a cool, dark place.
