serves 10

10 ounces bittersweet chocolate, such as Caillebaut, or Valrhona, coarsely chopped
10 ounces sweet butter, soft
9 egg yolks
1/2 cup granulated sugar
5 egg whites
1/4 teaspoon cream of tartar

In a large bowl, beat the egg yolks with 6 teaspoons sugar until lemony colored. Beat in the chocolate mixture.
