Abstract: The invention relates to a method for cooking food positioned in a receptacle, characterized in that: a predetermined volume V of denatured ethanol with a proof strength of at least 80• is poured on to the food, the ethanol is ignited and left to burn completely. The invention also relates to apparatuses for implementing the method, such as, for example an apparatus formed of at least a half-tube (3) closed off at each end by half-plates (4) in the shape of half-discs, each comprising a central cut-out (5) for guiding a skewer (2) or half-skewers (8) holding the food that is to be cooked.
