I don't typically use milk except for baking; however if I did It would reside in the bear resistant cooler, with the eggs, margarine, meat and beer.
Small things like peanuts go into Tang jars, because they pack into the ammo cans better (The white dots between the peanut jars, in the pic, are the tops of Tang jars)
The bulk "dry" foods; chips, cookies, crackers, sometimes bread, nuts, cereal, etc. gets stored when possible, in larges square (Planter's) peanut jars, placed in ammo cans (critter resistant if not bear proof)
The bagged chips and loaf bread/buns (bagged) get reclosed with spring clothes pins and are stored in ammo cans...
I find the 25mm (linked ammo) Bradley boxes to work best for this for week enders if more food needs to be carried I go for the even larger .50 caliber ammo cans... for very rough country travel, I repackage the beer cans into 25mm ammo cans; it keeps them from wearing holes in each other (better than their original cases) so I know that they will survive to the end of the trail.
A small container of olive or peanut oil is stored in the cook kit (missile container) for frying. if using a lot of oil (deep frying ..mmm French fries) its plastic bottle gets stored in an ammo can (after use it gets poured back into its bottle and goes back into the can).
The biggest down side to the ammo boxes/cans is their weight, but their ease of handling and sturdiness/critter resistance, keeps me using them... (way more attempts to get at our goodies have been made by chipmunks and raccoons than bears.
Enjoy!
