    • The invention concerns a method for controlling the duration of heating and/or cooking an undetermined amount Z of a given food product (5) placed in an oven chamber (1) comprising a heat source (2) and a sensor (4) for picking up a signal characteristic of the heating and/or cooking state of the food product. The invention is characterised in that it consists, after (A) supplying the heat source (2) at an initial moment t.sub.0 so that it delivers a predetermined constant power P.sub.0, in (B) measuring said characteristic signal at several successive moments over a measuring interval from said initial moment t.sub.0 to a final prefixed moment t.sub.c ; in (C) computing over this measuring interval the value S.sub.Zc of the integral of the characteristic signal measurements of taken in absolute value; in (D) deducing the residual time t.sub.r for heating and/or cooking for said undetermined amount Z of food product according to a predetermined polynomial equation linking the residual time t.sub.r to the value S.sub.Zc of the computed integral; and in (E) stopping the supply of the heat source when the residual time t.sub.r has elapsed.
