Makes enough for six 5-inch tartlets or one 10-inch tart. Imagine the best crust you can: butttery, flaky, and just a little sweet- and now imagine that it's chocolate through and through. Use this crust to fill the extrabagantly rich Chocolate Truffle Tartlets (recipe also posted), to fill with pastry cream or creme fraiche and top with fruits, or to create a grown-up ice cream pie, filled with superior ice-cream and drizzled with a bittersweet chocolate sauce.
