The invention provides methods and moulding devices for moulding three-dimensional products from a mass of foodstuff which is suitable for human consumption, in particular from a mass of meat, in particular chicken. The method comprises filling a mould cavity with a portion of the mass under the influence of a filling pressure exerted on the mass and for a filling period via a filling opening associated with the mould cavity, closing the filling opening of the mould cavity and holding the mass in the mould cavity for a fixing period. Then, the mould cavity is opened and the moulded product is removed from the mould cavity. The method uses fixing-pressure-exerting means which are designed to exert a fixing pressure which acts on the mass in the mould cavity after the filled mould cavity has been closed.
