1 cup/250 ml mascarpone or whipped cream cheese, at room temperature
1/2 cup/125 ml heavy cream
3 tablespoons sugar
Zest of 1 lemon, optional
2 egg whites
Fresh berries, for serving
Rub the cheese through a sieve to make smooth. Whip the heavy cream to stiff peaks with the sugar and fold into the cheese. Add lemon zest if using. Beat the egg whites to stiff peaks and fold them in to the mixture as well. Turn the mixture into cheesecloth-lined heart molds (these are porcelain with perforated bottoms, available in specialty kitchenware shops.) Set on a rack set in a casserole dish or on a baking pan, cover and refrigerate overnight to drain. Just before serving, unmold. Serve with more sweetened heavy cream poured over, and berries. Cook's Note: If you do not have a coeur a la creme mold, simply line a fine mesh sieve with cheesecloth and set over a bowl. It may not be heart-shaped but it will taste just as delicious.
