For cream, whip cream to soft peaks and stir in sugar. Chill until ready to serve.
For fruit, preheat oven to 400° F. Toss peaches, raspberries, blueberries and blackberries with superfine sugar and lemon zest and let sit for 10 minutes. Spoon into a 4 cup baking dish and bake for 8 to 10 minutes, just until hot. Remove from heat.
While fruit is roasting, prepare sugar. Bring sugar, lemon juice and water up to a boil in a saucepan. Without stirring, cook sugar until a light golden brown, brushing the sides of the pan with water occasionally.
To serve, top hot fruit with whipped cream, and pour hot sugar over cream. As the warm fruit and hot sugar comes in contact with the cream, it will melt slightly into the fruit. Serve immediately.
Yield: 1 4-cup baking dish. Makes 4 to 6 servings.
