Top this low-fat custard with a variety of seasonal fruits.
In a medium bowl, stir together flour, the 2 tablespoons sugar, and 1/4 teaspoon salt. Using a pastry blender, cut in butter until pieces are the size of small peas. Sprinkle 1 tablespoon of the cold water over part of mixture; gently toss with a fork. Push moistened dough to side of bowl. Repeat with remaining water, 1 tablespoon at a time until all dough is moistened. Form into a ball.
On a lightly floured surface, flatten dough with hands. Roll from center to edges, forming a circle about 13 inches in diameter. Ease pastry into an 11-inch tart pan with removable bottom, being careful not to stretch the pastry. Trim even with edge of pan. Prick pastry generously with tines of a fork. Bake in a 450 degree F oven for 10 to 12 minutes or until golden brown. Cool on wire rack.
For filling, in a heavy medium saucepan, stir together the 1/4 cup sugar and the cornstarch; stir in milk and egg product. Cook and stir over medium heat until mixture is thickened and bubbly. Cook and stir 2 minutes more. Remove from the heat. Stir in orange juice concentrate and vanilla. Cover surface of the filling with plastic wrap; refrigerate 3 to 24 hours or until thoroughly chilled.
Spread cooled filling in pastry shell. Cover; chill for 1 hour.
Arrange fruit as desired on top of filling. Combine honey and rum. Brush fruit with honey mixture. Serve immediately, or cover and chill for up to 1 hour. Before serving, remove side of pan. Makes 10 servings.
