Ingredients

• 5 ounces (142g) bittersweet chocolate

• 1 cup (227g) unsalted butter, softened

• 2 large (60g) egg whites

• 1/2 cup (100g) granulated sugar

3. Gradually add the room temperature butter, a tablespoon at a time, until it's fully incorporated.

4. Add the cooled melted chocolate and whip until fully combined.

Note:

• Use pasteurized egg whites if you have any concerns about using fresh egg whites.
