No one has done more to popularize mushrooms in America than Amy Farges, food writer and co-owner of the national mushroom distributor Aux Delices Des Bois. And now that Ms. Farges made sure mushrooms are available, she shows what to do with them. The Mushroom Cookbook and Primer is an inspiration-a mushroom extravaganza with 175 exquisite yet easy-to-make recipes, plus a Mushroom 101 guide to selecting, storing, cleaning, and cooking, plus a primer with full profiles and photographs of 40 exotic mushrooms. Full of sweet succulence, toothsome crunch, and haunting flavors from earthy to fruity to seafood-like, mushrooms offer the home cook a dazzling range of possibilities. Here are finger foods: Morels with Calvados, Ovoli and Fig Crostini, Wild Mushroom Bruschetta. Lighter offerings: Porcini Carpaccio, Cream of Asparagus Soup with Roasted Cremini, Blewitt and Crab Rolls. Glorious pairings: Risotto with Corn and Chanterelles, Sirloin Steak with Wine Caps, Mustard-coated Lamb Chops with Wild Oysters, Truffled Lobster with Cilantro Butter, Duck and Shiitake Tortillas. And the unexpected: Black Trumpet Biscuits, Portobello and Basil Salsa, Hen of the Wood Ravioli. A dozen fitting mushroomless desserts offer the irresistible finish.
