If fresh morels aren't available, substitute 1-ounce (about 3/4 cup) 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 into rings.
To clean morel mushrooms, place mushrooms in a pan or bowl. Cover with water; add a dash of salt. Soak for 10 to 15 minutes. Drain and rinse. Repeat two more times. Pat mushrooms dry.
