Cooking apple

Cooking apples are used primarily as an ingredient to make apple pies, summer pies and cider. They can be obtained from the Cooks' Guild or otherwise harvested from an apple tree grown from an apple tree seed in a fruit tree patch by a player with a Farming level of 27 or higher.

A basket of apples (which contains 5 apples) is used as payment to grow a Willow tree or to grow strawberries in the Farming skill. 4 baskets of 5 apples each is used as payment to grow a Banana tree in the Farming skill.
