3 cups mini marshmallows
1/2 stick unsalted butter, softened
9 ounces best quality semisweet chocolate, chopped into small pieces
1/4 cup hot water from a recently boiled kettle
1 cup heavy cream
1 tsp. vanilla extract
- Put the marshmallows, butter, chocolate, and water in a heavy-based saucepan.
- Put the saucepan on the stove, over heat, though keep it fairly gentle, to melt, stirring every now and again. Remove from the heat.
- Meanwhile whip the cream with the vanilla until thick and then fold into the cooling chocolate mixture until you have a smooth, cohesive mixture.
- Pour or scrape into 4 or 6 glasses or small dishes and chill until you want to eat. The sooner the better!
