Abstract: The invention describes a set of cooking utensils for steaming food, essentially a casserole or main part and another casserole or secondary part which is inserted into the main part, with the novelty that the secondary part remains suspended on some notches provided on the inner walls or sides of the main part. With this system of engagement, the secondary part can have a smaller size than in traditional designs, thereby reducing the cost and the complexity of its manufacturing and simplifying its cleaning and storage.
