A Bachelor’s Kitchen GuideFREEZER FOODS:Ice CreamIf you can't tell the difference between your ice cubes and your ice cream, it's time to throw BOTH out.
Frozen FoodsFrozen foods that have become an integral part of the defrosting problem in your freezer compartment will probably be spoiled (or wrecked anyway) by the time you pry them out with a kitchen knife.
IN THE FRIDGE:EggsWhen something starts pecking its way out of the shell, the egg is probably past its prime.
Dairy ProductsMilk is spoiled when it starts to look like yoghurt. Yoghurt is spoiled when it starts to look like cottage cheese. Cottage cheese is spoiled when it starts to look like regular cheese. Regular cheese is nothing but spoiled milk anyway—if you can dig down and still find something non-green, bon appétit!
MeatIf opening the refrigerator door causes stray animals from a three-block radius to congregate outside your house, toss the meat.
Unmarked ItemsYou know it is well beyond prime when you’re tempted to discard the Tupperware along with the food.
General Rule of ThumbMost food cannot be kept longer than the average life span of a hamster. Keep a hamster in your refrigerator to gauge this.
ON THE SHELF:Canned GoodsAny canned goods that have become the size or shape of a softball should be disposed of...very carefully.
PotatoesFresh potatoes do not have roots, branches, or dense, leafy undergrowth.
The Gag TestAnything that makes you gag is spoiled (except for leftovers from what you cooked for yourself last night).
BreadSesame seeds and poppy seeds are the only officially acceptable “spots” that should be seen on the surface of any loaf of bread. Fuzzy and hairy looking white or green growth areas are good indications that your bread has turned into a pharmaceutical laboratory experiment. You may wish to discard it at this time, depending on your interest in pharmaceuticals.
CerealIt is generally a good rule of thumb that cereal should be discarded when it is two years or longer beyond the expiration date, or when it will no longer fall out of the box by itself.
FlourFlour is spoiled when it wiggles, or things fly out when you open it.
PretzelsNormally eternal, pretzels may be discarded if they can no longer be picked up without falling apart. Otherwise, there’s nothing to stop you from eating a pretzel that the Pharaoh put down only 4,000 years ago.
RaisinsRaisins should not usually be harder than your teeth.
SaltIt never spoils. However, if you can’t chip off reasonable amounts from the block, maybe another box is in order, as fresh salt usually pours.
SpicesMost spices cannot die, they just fade away. They will be fine on your shelf, forever. Put them in your will.
VinegarIf your grandmother made it, it is probably still good.
EXPIRATION DATES:This is not a marketing ploy to encourage you to throw away perfectly good food so that you’ll spend more on groceries. Even dry foods older than you are may not need to be replaced yet. Perhaps you’d benefit by having a calendar in your kitchen.
