Spread each square with a scant 1 teaspoon of jelly. With each square of pastry turned like a diamond shape with a point facing you, arrange 2 slices of ham down the center of the pastry, then a slice of Brie then 4 or 5 asparagus spears so the ham Brie and asparagus all run in the same direction. Season with a little salt and pepper. Fold the left corner over the asparagus, brush it with egg, fold the right corner over the top. Arrange the pastries on a baking sheet in a single layer. Brush with more egg then sprinkle with sesame seeds. Repeat with the remaining sheet of pastry, jelly, ham, Brie, asparagus, egg and sesame seeds; place on the second baking sheet. Bake for 30 to 35 minutes until the pastry is golden brown and puffed. Let stand on the baking sheet for 2 minutes before serving. Serve hot. Makes 8.
