Preheat oven to 400 degrees F. Lightly coat two 4 1/2-inch individual pie plates, 10-ounce custard cups, or 10-ounce au gratin dishes with nonstick cooking spray; set aside.
In a small bowl, combine egg, flour, milk, and salt. Beat with a wire whisk or rotary beater until smooth. Immediately pour batter into prepared baking dishes. Bake for 15 to 20 minutes or until pancakes are puffed and well browned.
Meanwhile, place orange marmalade in a small microwave-safe dish. Microwave, uncovered, on 100 percent power (high) about 30 seconds or until melted.
To serve, top puffed pancakes with fruit; spoon melted marmalade over fruit. Serve warm.
