Cooking apple

From Freepedia

A cooking apple is an apple that is used primarily for cooking rather than eating fresh. They are generally a lot less sweet and a lot more sour than eating varieties, and have a firm flesh that doesn't break down too much when cooked.

Apples can be baked in an oven and served with custard or put into an apple pie or apple crumble. In the UK apples are boiled and mashed and served as apple sauce with roast pork.
