Le Creuset 2-1/2-Quart Round Doufeu. The doufeu is the original dutch oven, taking it’s name from the combination of the French doux and feu or “gentle fire.” Tight fitting lid is designed to hold ice cubes, so that the warm vapor from the simmering food meets the cool lid, promotion condensation. Dimples under the lid cause the condensation to drop back in to the lid continually basting the food in the pot. This process aids in creating a juicy and moist roast or cut of meat.
