I read the article, and will make these comments...
Use by dates...if canned goods, these can be generally ignored. Most canned goods will last and remain a healthy food well beyond the ‘expiration’ dates.
Cooking Oils...the only oil any of us should use for cooking is coconut oil. We have expeller pressed, naturally refined coconut oil that does not smell or taste like coconut. Coconut oil is made up almost entirely of medium chain saturated fats that cannot spoil if kept at ambient temperatures...coconut oil will still be edible long after any of us reading this are gone. It is healthy and should be a part of our diets. We are on our way to having several hundred pounds stowed away for when we can’t get it anymore.
Baking Staples...whole wheat flour will eventually turn rancid if it still has the germ in it. It keeps longer refrigerated or in the freezer. Most healthy flour is from sprouted spelt. We have access to organic sprouted spelt flour from an Amish mill. Baking soda will keep a long time if kept air tight, away from moisture. Arm & Hammer Baking Soda is Aluminum free, btw. Baking powder has an age limit that can be extended by keeping it in the freezer. We buy pure Mexican vanilla by the quart at very reasonable prices and have it stored.
Condiments...Grow your own horseradish and grind it as you need it. Turn fresh cabbage into sauerkraut. As the article says, buy whole peppercorns and grind as you need them. We buy RealSalt in 25 lb bags and have it stored.
Vegetables...grow your own as much as possible. A ‘root cellar’ will keep potatoes, carrots, beets, turnips, onions, garlic for months. Remember that sweet onions will not store well. Can your fresh tomatoes from your garden that exceed what you eat.
Meat and Fish...Freezing is a good option. So is canning. Make jerky out of beef or venison. Depending on where you live, remember that venison, rabbit, squirrel, geese etc are available if you hunt. Go fishing.
WE MUST NOT FORGET that if we are going to depending on electricity for water, refrigeration, heating (running the fans on the gas furnace) etc, we must become grid independent. There are various options for this, and is subject for another thread.
In closing, we are in the country, we have a well, and we have gas from a well for which we have mineral rights. This is our holeup place, our ‘bugout’ location. We are not threatened by earthquake or flood, and our location is defensible. We have a garden, and plenty of room for expansion. We have three horses that keep the garden in fertilizer. We have a prolific peach tree. We have cherry, apple and pear trees, and we are setting out raspberry and blueberry bushes. We grow asparagus, and once started, it keeps coming year after year.
There are some things we are stocking, like the coconut oil and a few other things that we will use for barter. Staples can be used for barter, never ammunition (my not so humble opinion).
We recycle all grease and fat from cooking. We make soap out of it. The soap is used for everything - in the shower, in the laundry, etc. Which reminds me, I need to get another hundred pounds of lye (sodium hydroxide).
We use hydrogen peroxide for many things, both health and household uses. We buy 50% food grade by the gallon, and we have this stocked too. We avoid chlorine bleach for health reasons.
Raw peanuts will last forever in the freezer. I pulled out one of three cheap pint freezer baggies a few days ago and made a batch of peanut brittle. Tasted fine raw from the bag and the brittle was devoured by the next morning. Ok, they were from 4 little plants lil’ miss brought home from preschool in 1995 so I’d kept them for sentimental reasons. I might see if they’re still viable for the garden.
