This tart is not only pleasing to the eye but the taste buds as well. The crust is meant to be hand-crimped in a rustic fashion, so don't worry about perfection. I used peaches, strawberries and blueberries, but good substitutes for the berries would be raspberries or blackberries. A sprinkling of powdered sugar atop this tart makes for elegant presentation. Preparation time does not include cooling time.
