Abstract: A method of processing a product, such as food product, is disclosed. Untreated product is placed inside a bottom-unloading basket that is, in turn, placed within a covered vessel. For processing a food product, the invention uses a porous steamer apparatus for insertion into a covered cooking vessel. The steamer apparatus is comprised of two unfastened pieces, a basket and a support base, each of which has a plurality of small holes through which steam, but not food product, may pass. The basket holds the food product, is roughly cylindrical in shape, has an open-ended top and an open-ended bottom, and rests firmly upon, but is not fastened to, the support base during the steam-cooking process. The support base has an inverted conical shape and a vertical pole that has a hook-shaped upper terminus and that is integrally-connected to and protruding above and below the uppermost point of the support base.
