Allow 1 hr chill time in addition to cook/prep time. Make-Ahead Tip: Cool the baked pastries, then wrap and freeze up to 1 month. To serve, place frozen pastries on an ungreased baking sheet. Bake, uncovered, in a 350 degree F oven for 20 minutes or until heated through. Note: if fresh morels aren't available, substitute 1 1/2-ounces dried morel or porcini mushrooms. In a small bowl, cover the dried mushrooms with hot water. Let stand for 20 minutes. Rinse under warm running water; squeeze out excess moisture. Slice the mushrooms.
