"Tartiflette has the tang and satisfaction of macaroni and cheese baked until it forms a chewy crust, the pure pleasure derived from a bowl of creamy mashed potatoes and a flavor that could only come from 500 years spent perfecting cheesemaking." A traditional dish of France's Haute-Savoie region, it can be tricky to find a version that's delicious and not just served up for tourists. Mmmm…tartiflette.
