We're getting ready to pack up the house and move back overseas -- our stock of bittersweet chocolate has dwindled to nothing, but we still have a fair amount of good-quality unsweetened chocolate. How can this recipe be adjusted?
1 1/2 cups heavy cream
1/2 cup whole milk
3 ounces bittersweet chocolate, finely chopped
1 ounce unsweetened chocolate, finely chopped
4 egg yolks
3 tablespoons sugar
1/8 teaspoon kosher saltA@@
