Pronunciation: [ma-ROHN glah-SAY]
Marron is French for "chestnut." Marrons glacés are chestnuts that have been preserved in a sweet syrup. They can be found in jars or cans in most supermarkets and are quite expensive. They're eaten as a confection, chopped and used to top desserts such as ice cream and mixed fruit or used to make desserts such as the rich mont blanc.
