Due to the superior construction of the Staub cocotte lids, less humidity can escape during the cooking process. 10% more moisture is retained inside the Staub cocotte after 55 minutes cooking time than in products from competitors.* The self basting system consisting of distributed spikes over the whole inside flat lid ensures a continuous rainfall effect over the food inside the cocotte. The Staub self basting system in the lid is 9 times more effective than conventional lids.***Tested by Cetim Cermat (11/2009)**Tested by R&D Department of ZWILLING J.A. Henckels (11/2009)
