When Chez Panisse chef Cal Peternell realized his college freshman son wasn’t prepared to cook on his own, he came up with this book of recipes, just twelve that he feels comprise the heart of a home. The idea is to read each recipe and feel that someone cares that you not feel intimidated, and roots for your success. Recipes cover toast and eggs; beans; salads and dressings; pastas; soups; chicken; braises; grilling; sauces; and cake. We love eggs for any meal, so we’ve focused this week on Cal’s recipe for frittata with lots of vegetables.
