The is a truly beautiful tart that is delicious just out of the oven, warm, at room temperature, or even slightly chilled. If you’re serving it as a starter, cut it into 6 portions; if it’s the main dish, serve it with a lightly dressed small salad. Recipe is from Dorie Greenspan's great new cookbook, "Around my French Table", where Dorie calls it Gerard's Mustard Tart. Use Dorie's Basic French Tart Dough/Pate Brisee (recipe #440320).
