The Perfectly Preserved Pie is a consumable item in Fallout 4.
Gameplay
The pie's most significant difference from many other foodstuffs found throughout the wasteland is its preservative-filled nature, lacking any radiation when compared to most other pre-War foodstuffs.
Obtaining
The perfectly preserved pie can be obtained from any Port-A-Diner, with a small chance of dispensing. Obtaining the pie on any particular attempt is determined by the formula...
- ...where...
- chance: the percentage chance of obtaining the pie
- luck: the Sole Survivor's Luck, even if the Port-A-Diner is operated by a companion
- attempts: the number of previous attempts made to obtain the pie
- ...thus, even with a Luck of 10, there is still only a 2% chance of obtaining the pie on the first attempt.
By cumulative probabilities, a Sole Survivor with Luck 5 has a 50% chance of obtaining the pie within the first 36 attempts. Luck 10 reduces that to 26 attempts, while Luck 1 doesn't reach those odds until 49 attempts.
Depending on the Sole Survivor's Luck, it takes between 75 and 105 attempts to reach a 95% chance of getting the pie, and 109 to 140 attempts to reach a 99.5% chance of getting the pie.
Locations

Notes
- During the quest The Big Dig, Mel will comment on the pie upon encountering the Port-A-Diner located in The Dig, saying that he would not trust anything that has been perfectly preserved for 200 years.
- In Survival mode, the pie has no food value, owing to a data keyword bug.
- There is a machine located in the Nuka-World Junkyard that will always give the pie on the first attempt.
