# Directions:
01 - Place a small plate in the freezer to use later for testing jam set.
02 - In a large heavy-bottomed saucepan, combine blackcurrants and lemon juice. Gently crush some berries with a potato masher to release their juices.
03 - Add sugar and stir to combine. Let the mixture sit for 10 minutes to draw out additional juices from the fruit.
04 - Place the saucepan over medium heat. Stir until the sugar dissolves completely.
05 - Increase heat to high and bring the mixture to a rapid boil. Stir frequently to prevent sticking and ensure even cooking.
06 - Boil vigorously for 10 to 15 minutes, skimming off any foam that rises to the surface. Test the setting point by placing a drop of jam on the chilled plate, waiting 1 minute, then gently pushing with your finger—if it wrinkles, the jam has reached the proper consistency.
07 - Remove from heat and let the jam sit for 5 minutes, stirring occasionally to distribute fruit solids evenly throughout.
08 - Ladle hot jam into sterilized jars, leaving approximately 0.2 inches of headspace. Seal jars immediately.
09 - Allow jars to cool at room temperature. Label with the preparation date and store in a cool, dark place.
