Flour (Fallout 3)

To find flour, go to Tenpenny Tower and trade with Lydia Montenegro. If you have already had her kicked out of Tenpenny Tower you can find flour by going to Andale, head east to the road. Next head NE along the road past the truck and you will see a diner off in the distance. There is a bag of flour located on the shelf in the diner.

Flour can also be found in a mailbox in Minefield.

Flour is used to make Mississippi Quantum Pie. It should be noted that Flour is considered a miscellaneous item, and not a food item.
