# Steps:
01 - Rinse the black currants thoroughly under cold water and remove any stems.
02 - In a medium saucepan, combine the sugar and water. Bring to a simmer over medium heat, stirring until the sugar dissolves completely, approximately 3-4 minutes.
03 - Add the black currants to the saucepan and simmer for 5 minutes until the berries are soft and starting to burst.
04 - Remove from heat and let cool slightly. Blend the mixture with an immersion blender or stand blender until completely smooth.
05 - Press the purée through a fine-mesh sieve into a bowl to remove seeds and skins. Discard the solids.
06 - Stir in the lemon juice. Taste and adjust sweetness if necessary.
07 - Cover and refrigerate the mixture for at least 2 hours until thoroughly cold.
08 - Pour the chilled mixture into an ice cream maker and churn according to manufacturer instructions, typically 20-30 minutes, until thick and slushy.
09 - Transfer the sorbet to a freezer-safe container and freeze for at least 2 hours until firm.
10 - Before serving, let the sorbet sit at room temperature for a few minutes to soften slightly for easy scooping.
