What each ingredient does
- Unsweetened chocolate
- Provides the main chocolate flavour and body of the sauce as it melts.
- Powdered sugar
- Adds sweetness and dissolves easily into the melted chocolate for a smooth sauce.
- Boiling water
- Loosens the melted chocolate and sugar into a pourable liquid.
The step that matters
Cooking to the consistency of molasses. Chocolate sauce thickens as it cooks and cools, so stopping too early leaves it thin, while overcooking can make it stiff. Gentle heat in a double boiler helps prevent the chocolate from scorching or seizing.
