Crispy Potato, Artichoke, Leek, and Gruyère Tart
Tart crusts can be made from other ingredients, including cooked spaghetti, polenta, and rice, or in this case, thinly sliced potatoes. The goal is to make a crisp, shallow vessel that will contain the filling without leaking. This is especially important when a custard filling is used. The baby artichokes in this recipe can be replaced by thinly sliced artichoke hearts.
