Pork pie

Pork pie can be made by using 3 pieces of cooked bacon on a pie shell and cooking the resulting uncooked pork pie, requiring 74 Cooking and giving 210 experience. It heals up to 1350 life points depending on your Constitution level. It will boost both your Farming level and Summoning level by 5.

Uses
This boost is the best Farming boost in game, providing a consistent +5 boost regardless of level. (The Stranger plant can only boost a maximum of +4 even at Level 99 Farming.) However, the item is quite hard to obtain over the Grand Exchange, so making one yourself is a viable option.

The pie also boosts your summoning points. Although you gain a Summoning boost of +5 which is visible, this boost is merely an increase in Summoning points, and will not allow you to perform any tasks requiring a higher summoning level than what you have initially, other than opening Summoning-affiliated ancient effigies. The summoning point boost can be useful when renewing a familiar while fighting or skilling for a long time in a location far removed from any mini-obelisks.
