Reblochon, a cheese enjoyed since the 14th century, is aged in cellars or caves in the Haute Savoie Alpen mountain range. Turned every two days and washed with whey to speed the ripening process, it produces a soft, washed-rind cheese made from unpasteurised cow's milk. Reblochon has a creamy soft texture that remains in mouth. It is an essential ingredient of tartiflette, a Savoyard gratin made from potatoes, cream, onions and bacon.
