I recently came across a company in france that was selling a tart press. It has a sheet of moulds(60 or so )that you would cover with sweet dough and press down with a top mold. Trim the excess and bake. It came in many sizes( 2", barquettes) They were selling it for $100 u.s.
The company also had a website that sold many fine foods including prebaked tart shells.
Any help would be gratefull in locating them again.
