Potato & Leek Gratin

A mandoline will slice the potatoes quickly and to the exact same thickness, though a sharp knife will also work. Instead of burying the potatoes and leeks in cream, a drizzle of milk is added to every layer of the gratin; the potatoes get wonderfully crisp and tender, and the cheeses form a melty, golden crust. The result is a rich, rustic potato side with contrasting flavors and textures—a bit of crunch to round out the stuffing, sauces, and mashes on the plate. Reheat leftovers in the oven until crisped and warmed through, and then serve with eggs and a side of fruit for breakfast.
