Ingredients:
- 2 cups water
- 1 cup granulated sugar
- 1/2 cup unsweetened cocoa powder
- 4 oz dark chocolate (60% cocoa or higher), chopped
- 1 tsp vanilla extract
- 1/4 tsp fine sea salt
- 1 tsp instant espresso powder
Instructions:
- Combine water, sugar, cocoa powder, and espresso powder in a saucepan over medium heat.
- Whisk constantly until the mixture reaches a gentle boil and the sugar is fully dissolved, then remove from heat immediately.
- Whisk in the chopped dark chocolate, vanilla extract, and salt until the chocolate is completely melted and the mixture is glossy.
- Pour the base through a fine-mesh strainer into a bowl to remove any undissolved bits.
- Allow the mixture to cool to room temperature, then chill in the refrigerator for 2 hours.
- To freeze, either churn in an ice cream maker according to manufacturer directions, or pour into a shallow container and freeze, whisking or blending every 30 minutes for 4 hours to break up ice crystals.
