# Directions:
01 - Rinse the black currants thoroughly under cold water and remove any stems or leaves.
02 - In a large heavy-bottomed saucepan, combine the black currants and water. Bring to a simmer over medium heat, stirring and mashing occasionally for 15–20 minutes until the fruit is very soft and releases its juice.
03 - Set a fine-mesh sieve or jelly bag over a large bowl. Pour the cooked fruit and juice into the sieve and let it drain for at least 2 hours or overnight in the refrigerator without pressing to maintain clarity of the jelly.
04 - Measure the collected juice, which should yield approximately 3 cups. Return the juice to a clean saucepan and add the sugar and lemon juice, using a 1:1 ratio of juice to sugar by volume.
05 - Stir the mixture over low heat until the sugar dissolves completely, ensuring no crystals remain on the bottom of the pan.
06 - Increase the heat and bring to a rapid boil. Boil hard for 10–12 minutes, or until the jelly reaches 221°F on a candy thermometer or passes the wrinkle test on a cold plate.
07 - Remove from heat and skim off any foam that has accumulated on the surface.
08 - Carefully ladle the hot jelly into sterilized glass jars, leaving ¼ inch headspace. Seal immediately with lids.
09 - Allow the jars to cool at room temperature undisturbed. Once cooled, store in a cool, dark place.
