Steps
- Put 225g of finely chopped semisweet chocolate, 1 cup of heavy cream, 1 tablespoon of sugar, and 1 tablespoon of unsalted butter in a microwave-safe bowl.
- Microwave on medium power for 1½ minutes and stir. Microwave for 30-60 seconds more, until about three-quarters melted, then stir until smooth, letting the remaining heat melt the rest of the chocolate. Serve warm, with fruit for dipping.
