Raw summer pies are used to quickly train Cooking and Magic by using the Bake Pie spell. They are made by using the ingredients (Strawberry, Watermelon, Cooking apple) on a Pie shell, in that order. To avoid losing money, test out the profit of making one pie before you do them in bulk. You can then sell the pies on the Grand Exchange. To maximize your profit, buy one raw summer pie at the instant price, and then sell all of yours for that price.
