Cider, or hard cider, is an alcoholic beverage made from fermented juice of specially cultivated "cider apples" that can be used to add flavor and moisture to various meat and fish dishes. In French cooking dishes from Normandy ("Normande") often contain apples and may be moistened with cider. It may be used in place of white wine in many recipes.
In North America (USA and some, but not all, parts of Canada) cider is unfiltered unfermented (non-alcoholic) apple juice and the alcoholic version is known as "hard cider".
For uncooked usage of cider, see the numerous warnings on the alcoholic drink page.
