The Le Creuset Doufeu is made from high quality enamalled cast iron. 
 
The name of the Doufeu is taken from two French words: doux and feu, meaning gentle fire, or gentle heat.  It is ideally suited to all meats and poultry and particularly to those meats where the moist gentle heat will completely soften otherwise tough fibres. 
 
To achieve these succulent results, the recessed lid is filled with ice blocks, and placed on the hob.  Once the contents are hot, the steam produced rises until it meets the cooled recessed lid.  Here the steam is cooled and converted back to liquid.  The projections on the underside of the lid guide the liquid directly on the food so that it is bathed in a mist of tiny water droplets.
 
Foods remain moist and flavours develop to an intense degree.
