Marbleized Lemon Tart with Sage
Anyone who samples this sunny lemon tart can tell you that appearances don’t deceive: The dessert tastes every bit as bright and springlike as it looks. Egg yolks, sugar, and freshly squeezed lemon juice create a velvety curd that is poured into a crunchy cornmeal shell flecked with lemon zest and fresh sage. Before it is chilled to set, crème fraîche is dolloped over the curd filling and teased into a swirling pattern with a wooden skewer.
