Accomplished home cook Nadine Levy Redzepi is married to René Redzepi, chef of acclaimed restaurant Noma in Copenhagen. Lest you think that Downtime must therefore be complicated, be disabused: the recipes are straightforward, often with notes like "Congratulations: You've made a tart shell," followed by variations on the dish. The recipes are homey, perfect for families and friends--comfort dishes like Roasted Ratatouille with Orzo, Warm Potatoes with Greens and Herbs, Baked Salmon with Thyme and Thin Potatoes, Chocolate Chunk Cookies. She's a fan of butter basting, and finger foods to start a meal (Green Asparagus with Poached Egg). Her Portuguese Pork Chops and Rice uses three tablespoons of butter, one lemon and six garlic cloves--the essence of simplicity, and the sum greater than the parts. The recipes are easy enough for weekday meals, and will elevate any cook's repertoire. --Marilyn Dahl
