My taste in food is pretty simple, writes Sara Hainsworth of Frederick, Maryland. I'm a meat-and-potatoes — and chocolate — kind of person. This lemon tart recipe is my husband, Greg's, specialty. Greg and I cook together a lot, which is fun and makes weeknight dinners and cooking for friends easier to manage now that we're starting our own family. For a chocolate-fix variation, Sara suggests filling purchased three-inch chocolate tartlet shells with the lemon curd. Or brush melted sweet chocolate over the graham cracker crust before filling. Begin this recipe four hours to one day ahead.
