A sauteuse has flared sides, which gives more surface area exposed to the air and makes reduction faster. If you want to reduce a stock, a cream sauce or a wine so that it concentrates without constantly stirring, this is the right vessel.
At 4.7 litres and in CopperBond construction with a pure copper core and five layers, where the heat rises and falls with the actual temperature rather than the inertia of the metal. Handmade in Italy, induction-safe, oven-safe to 315 degrees. Hand-washing recommended.
