Abstract: Method and apparatus for determining the doubling in volume of a rising dough includes a horizontal beam placed across the edge of the bowl which has a retaining notch for a vertical calibrated stick whose end is placed on the top of the dough to ascertain its volume either in an unrisen or risen condition. Since the bowl has nonvertical or sloping sides, the measuring stick is calibrated with a nonlinear scale to compensate or to correspond to the sloping sides. Thus the measuring stick has marked on its scale, for example, the number of cups of dough in the bowl. A measurement is initially made before the dough has risen and then doubled to provide the user with a measurable number which periodic checking will indicate when the dough has increased to that desired volume.
