A food product is frozen at least partially by contacting a surface area (4) of a chilled tray (1). The tray (1) consists of a plurality of elements (2, 3). The elements are juxtaposed to form the surface area (4), they are further movable relative to each other for changing of the relative position of at least one element at a time, and finally they each occupy such a small surface in the surface area that the change of relative position is possible also after the food product part contacting the tray has been frozen. |
