Chantilly Cream

2 half pints whipping cream

1 tbs Kahlua

1 tbs Grand Marnier

1 tbs powdered sugar

1 tbs sour cream

Zest of 1 orange

Whip cream at large speed in electric mixer. When peaches are stiff enough, add remaining ingredients and whip for 10 seconds - just enough to blend. Chill. Serve with peach tart.
