Redberry pie

Redberry pie is a pie that can be cooked at level 10 Cooking. It is used in The Knight's Sword quest, to bribe Thurgo, the Imcando dwarf, to help you (see quest article for details) make a sword. Also, giving one to Ramarno will reward you with 1000 Smithing experience in Defender of Varrock. A good place to prepare it is near the windmill north of Lumbridge. You can prepare flour there, and Beefy Bill can supply you with pots, redberries, pie dishes and water.

Cooking
A player may cook a redberry pie once they are level 10 in cooking. To cook a redberry pie, a player must get some grain and turn it into flour at a mill. The flour must be gathered with a pot then mixed with water to make (pastry) dough. Note that the water should come from a vessel, like for instance buckets, vials, waterskins, bowls, jugs...

Then a player must obtain a pie dish(which can be found in the Varrock Kitchen) and use the pie dough with it to make a pie shell. The player must find redberries and put them into the pie shell to make uncooked berry pie. Upon cooking it on a range or stove, the player receives 78 cooking experience if they succeeded in cooking. Players can accidentally burn the uncooked pie while cooking until they reach level 50 in cooking.

The redberry pie heals 50 life points when a slice is consumed. Like all pies, it is consumed in two parts. Therefore, one pie heals a total of 100 life points.

Since they sell in the grand exchange for high prices it may be a good way to earn money.
