- 1/2 pound blackberries
- 1/2 pound granulated sugar
- 1/4 cup blackberry liqueur (or substitute crème de mûre)
Combine berries, sugar, and liqueur in a small saucepan, and bring to a simmer over medium heat. Let cook until syrupy and reduced by half, about 10 minutes.
Transfer to a blender or food processor, and purée until smooth. Strain through a fine mesh sieve, pushing on the mixture with a rubber spatula. Set aside to cool.
