Place couverture chocolate directly in a medium-sized heatproof bowl. If you use a chocolate bar, chop it finely before adding it to the bowl.
8 ounces dark chocolate
Heat cream in a small saucepan on the stove or in a heatproof vessel in the microwave until steamy.
1 cup 35% whipping cream
Pour the hot cream over the chocolate. Wait for 5 minutes. Whisk until smooth and creamy. Cool to room temperature before using as a drip or for a tart, or refrigerate before whipping or using as filling.
