ABSTRACT:
Fluid comestibles are prepared from substances, particularly roast and ground coffee, contained in cartridges by supporting a peripheral portion of a first surface of a sealed cartridge with a holder which has a base which includes a grille and relief surface element so that the remainder portion of the first surface is positioned adjacent the relief surface element. An opposing cartridge surface is pierced for injection of water into the cartridge while maintaining the base in the position adjacent the first surface, and while maintaining the base in a fixed position, water is injected under a pressure of greater than atmospheric pressure into the cartridge to deform the first surface remainder portion against the relief surface element first to press the first surface against the relief surface element and to wet and compact the substance and then to tear and open the remainder portion of the first surface for flow of fluid comestible from the cartridge and through the grille in a plurality of streams.
