A cooking apple or culinary apple is an apple that is used primarily for cooking, as opposed to a dessert apple, which is eaten raw. Cooking apples are generally larger, and can be tarter than dessert varieties. Some varieties have a firm flesh that does not break down much when cooked. Culinary varieties with a high acid content produce froth when cooked, which is desirable for some recipes.
Apples can be cooked down into sauce, apple butter, or fruit preserves. They can be baked in an oven and served with custard, and made into pies or apple crumble. In the UK roast pork is commonly served with cold apple sauce made from boiled and mashed apples.
