# Directions:
01 - In a small saucepan, combine the black currants, sugar, and 1/4 cup water, stirring to mix evenly.
02 - Bring to a gentle simmer over medium heat, stirring occasionally. Cook for 6 to 8 minutes until the currants burst and the mixture thickens slightly.
03 - Mix the cornstarch with 1 tablespoon cold water in a small bowl until smooth to create a slurry.
04 - Stir the cornstarch slurry into the simmering sauce. Continue cooking for 1 to 2 minutes until glossy and lightly thickened.
05 - Remove from heat. Stir in the lemon juice and vanilla extract until fully incorporated.
06 - Pour the sauce through a fine mesh sieve to remove skins and seeds for a silky finish. Cool to room temperature. The sauce will thicken further as it cools.
