A Pie is any one of several food items that players can make with the Cooking skill. They all take two bites to eat. After both bites of the pie have been eaten, a pie dish remains. This dish can be used to make another pie.
Pies heal from 12.5 (for redberry pies) to 118.7 (for summer pies) life points per bite, and are made with pastry dough and a pie dish, along with other ingredients for the filling. One interesting note about pies is that players can eat one slice of pie after another in quick succession.
Players with level 65 magic and who have completed Lunar Diplomacy can use the spell Bake Pie, which cooks pies with a 100% success rate. It must be cast one pie per cast, though one click will cast it one spell at a time on every unbaked pie in your inventory. Although uncommon, this spell can yield quick yet expensive cooking XP.
