# Step-by-Step Guide:
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 constantly until the sugar dissolves completely, approximately 3 to 4 minutes.
03 - Add the black currants to the simmering syrup and cook for 5 minutes until the berries soften and begin to burst.
04 - Remove from heat and allow to cool slightly. Blend the mixture using a stick blender or traditional blender until smooth.
05 - Press the puree through a fine-mesh sieve into a clean bowl to remove seeds and skins. Discard the solids.
06 - Stir in the fresh lemon juice. Taste the mixture and adjust sweetness as desired.
07 - Cover the bowl and refrigerate for at least 2 hours until completely chilled.
08 - Pour the chilled mixture into an ice cream maker and churn according to manufacturer instructions, typically 20 to 30 minutes, until the mixture reaches a thick, slushy consistency.
09 - Transfer the churned sorbet to a freezer-safe container and freeze for at least 2 hours until firm.
10 - Before serving, allow the sorbet to sit at room temperature for a few minutes to soften slightly for easier scooping.
