To make Garden pie:
Mousse pie doesn't exist in Runescape
Peach pie does not exist in RuneScape.
Like other pies, you eat a garden pie in two bites. Each bite heals 60 life points.
Make a pastry dough, use it on a pie dish. Use a redberry on it and cook the unfinished pie.
You make an uncooked apple pie from using dough with a pie pan and using a cooking apple with the pan.
You can get some in the Cooking Guild on one of the floors, you can make a full apple pie there provided you have the Flour.
You can't make a black beery pie. There aren't any black berries. Non members can make Red-berry Pie Meat Pie Apple Pie Members can make Mud Pie Garden Pie Fish Pie Admiral Pie Wild Pie Summer Pie
you can make one anywhere and you can find red berries at the walls of varrock
There are several places on Runescape to buy a pie dish. From the Grand Exchange, the general stores, npcs , ect.
Go to G.E in Varrock and buy your pie dishes there.
Nope, the pie goes with the dish.
The Apple Pie heals 70 Life Points per slice on RuneScape. That is a total of 140 Life Points healed per pie.
