Abstract: A method determines a performance index of a cooking vessel subjected to a heating power, the index being representative of the capacity of the vessel to distribute the heating power in a homogeneous manner, the vessel including a bottom and a lateral wall furnished with an external face. The method includes a) subjecting the bottom of the vessel to a heating system, b) measuring and recording at regular time intervals the temperature at least three points of predetermined altitude of the external face until the stabilization of at least one of the measured temperatures at each time interval at the level of the at least three points, c) calculating and recording in the course of the time taken for the temperature of the external face to rise, the difference between the maximum temperature and the minimum temperature measured, d) determining the performance index based on the calculations and recordings.

Abstract: A method for cooking a food including free water, uses a cooking vessel having at least one cooking surface, the cooking surface being such that a drop of distilled water can form a contact angle with the cooking surface that is greater than or equal to 150° at ambient temperature, and the food being such that its water activity aw is greater than or equal to 0.5. The method includes heating the cooking surface to a minimum temperature of 125° C.; placing the food on the cooking surface; and cooking the food on the cooking surface.

Abstract: Provided is a method for determining a performance index of a cooking utensil (1a, 1b, 11) for a predetermined cooking temperature with, the aim of assessing nutritional gain, said cooking utensil comprising a bottom (2a, 2b, 10) having a cooking surface (3a, 3b, 10a).
