Process for preparing a layered multi-component food product

A process for preparing a layered multi-component food product comprising introducing a quantity of a first food component into an open-top container so that the first component is contained in the container and has a top surface level at a position beneath the top of the container and so that space is provided in the container for introduction of a second food component into the container, wherein the first food component is one which solidifies upon being cooled and which, upon introduction, is not in solid form, and within 30 seconds after introduction of the first food component, sequentially:

• (i) applying CO.sub.2 snow to the top surface of the first food component, which is not in solid form, to provide a complete and uniform CO.sub.2 snow-cover contacting the first food component top surface sufficient to frost the surface and obtain a portion of the first food component that is solidified from its top surface down to a depth sufficient to support a second food component having a density which is at least 0.2 kg/dm.sup.3 greater than the density of the first food component;
• (ii) applying suction from a mechanical unit source of suction directly to unsublimated residual snow-cover to remove the residual snow-cover from the top solidified surface of the first food component;
• and
• (iii) introducing a second food component, which has a density which is at least 0.2 kg/dm.sup.3 greater than the density of the first food component, into the container and onto the top solidified surface of the first food component.
