In our backyard resides a prolific lemon tree. We are forever trying to find new ways to incorporate these lovely yellow fruits into our culinary endeavors so that none go to waste. My 13-year-old daughter, Audrey, knows my love of all things sweet. She decided to test her baking skill by combining two of my lemony favorites: lemon bars and lemon meringue pie. After several intense hours in the kitchen (warding off her horde of brothers), these delicious bars were born. —Monica Fearnside, Rancho Palos Verdes, California
