Mushroom gâteau

This mushroom-laden stack of crepes—for which it’s worth shopping for an assortment of mushrooms—is a perfect appetizer or accompaniment to roast veal or other simple meat dishes; sauce it with the mushroom syrup from the preceding recipe or any vinaigrette. It’s best to prepare the cake in advance, then refrigerate it even overnight, before reheating; this will make it really easy to slice, and the reheating will crisp up the top nicely.
