Sautéed Black Trumpet (or Horn of Plenty) Shreds

Dark, chewy slivers of mushroom resemble swirls of black seaweed. They taste as exotic as they look—but surprisingly mild. A spoonful strewn over white fish fillets, grilled salmon, pale veal scallops, or calf’s liver makes a simple dish special. The springy mushrooms barely shrink in cooking, so even a small investment (they are expensive) will make a dramatic difference.
