Calville Blanc is an ancient French apple, which crossed the Atlantic early in the history of the New World and soon gained a following amongst discerning North American apple enthusiasts. It is not the best looking apple, but you grow this one for the kitchen not for the fruit bowl - it is a cooking apple of the highest quality.
Calville Blanc keeps its shape when cooked. If sliced thinly it can be used for the classic French "tarte aux pommes" - as found in the window of any French patisserie shop. If cut into small pieces it cooks down into a thick textured puree with a superb rich aromatic flavor. It does not keep long, and is best used within a month or so of picking.
Like many good culinary apples, Calville Blanc produces a good juice with a sharp but balanced flavor. Calville Blanc is noted for its high vitamin C content.
