Saint-Marcellin cheese, walnuts and ravioles: the Saint-Marcellin region is home to several stars of the gourmet Isère region.
- Saint-Marcellin is a small, round and creamy cheese made from cow's milk. The maturing process produces two types of Saint-Marcellin: dry, typical of local tradition; and soft, with a melting texture due to a longer maturing process. www.fromage-saint-marcellin.fr
- The Grenoble walnut, awarded recognition for its geographic origins (AOP) in 1938, is grown in the lower Isère valley. Three varieties are eligible for the AOP: parisienne, mayette and franquette. They can be eaten alone or with other food such as cheese or chocolate. Local chefs and pastry cooks use them in a wide range of recipes. www.aoc-noixdegrenoble.com
- Ravioles are like raviolis, small square pillows of dough stuffed with cheese and herbs. They are famous all over France. The technique for cooking them is very precise: they are plunged in boiling water or broth for one minute, and no more. You can buy them in Isère at Les Ravioles du Dauphin in Chatte.
