Pommery mustard is a brand of gourmet mustard that is manufactured by the Pommery family of Meaux, France. Also called Moutarde de Meaux or Old Mustard, this brand of mustard is made by keeping the whole grain mustard seed intact, which gives the prepared mustard its distinct, gritty texture.
Pommery mustard also includes mustard bran, vinegar, water and spices. It is thicker than other types of mustard, which makes it ideal as a base for vinaigrettes or as a crust for roasted poultry, veal or lamb dishes. Pommery mustard is sold in stoneware jars with either a wax or plastic seal.
