It includes at least two solid bottomed pans with a vertical wall portion and an open top, plus at least one sifting device having a perforated bottom portion with a vertical wall portion and an open top. The bottom portion of the solid bottomed pans also include a plurality of projections to prevent clogging of the perforations in the sifting device.
