Flour (Fallout 3)

Flour can be used as Rock-It Launcher ammunition. However, its more important use is as an ingredient in Mississippi Quantum Pie. It is not listed as a food item, but as a miscellaneous item.

There is only one guaranteed sample of flour out in the world. It can be found in a diner roughly north of the Nuka-Cola Plant and west of the Red Racer Factory. In addition, several vendors will sell flour:
 * Gary Staley and Seagrave Holmes in Rivet City
 * Lydia Montenegro in Tenpenny Tower
 * Moira Brown in Megaton
 * Knick Knack in Little Lamplight
 * Michael Masters in Warrington Station
 * Karl in Meresti Metro Station

If flour is needed, it is worth checking the inventory of any other vendor or scavenger as well, as there is a small chance it will be available for sale from these individuals.

It can also be found in the kind of random loot found in schools and kitchens.
