Abstract: A mold for food preparation, in particular for cake dough or similar, includes a semi-cylindrical rigid wall forming a trough and open at the two ends of same, and two transverse end walls, complementary to the trough, to form with the trough, a container open at the top and closed at the transverse side ends. The semi-cylindrical wall and the transverse walls are detachably associated. The mold further includes two sealer, each configured to engage one of the end edges of the trough. Each sealer is associated with a flat rigid plate to form, with the corresponding rigid plate, one of the transverse walls, and includes a peripheral groove configured to receive and engage the corresponding peripheral edge of the semi-cylindrical wall in the shape of a trough.
