What each ingredient does
- Unsweetened chocolate
- Provides the main chocolate flavor and fat that gives the sauce its richness.
- Powdered sugar
- Adds sweetness and dissolves quickly into the hot water and melted chocolate.
- Boiling water
- Thins the melted chocolate and sugar into a smooth, pourable sauce.
The step that matters
Cook until the consistency of molasses. As water evaporates, the sugar becomes more concentrated and the sauce thickens. It thickens further as it cools, so stopping at the right point matters for the final texture.
