The answer is, the manufacturer I want isn’t taking any more dealers right now and I don’t like a lot of what’s out there. Anyway, you can get “survival food” at lots of places. I’m not a big fan because they are all very salty and usually has a lot of soy in it. With the supply line issues right now, getting it is also difficult and expensive. It’s expensive because it packaged meals, just add hot water. That’s great for short term emergencies. Non-freeze-dried food requires much more preparation, a variety of ingredients, and usually a working kitchen. So, what to do? The basic rule is eat what you store. There is a lot of food at the grocery store that lasts for years. All canned foods usually last 2 years. Vacuum packed frozen foods in heavy bags lasts a year or two. We ate a 2 year old frozen turkey last Thanksgiving and it was perfect. Remember to buy things over time so the expiration dates are not all at the same time. Also, expiration and best by dates are not when the food goes bad. Things with oils in them are a different story, oil goes rancid over time. So for less than $100 at a big box grocery store you can get the basics like: beans, rice, canned chicken, cream of condensed soups, canned veggies, spaghetti & sauce, etc. With the basics and spices you should already have; you can make lots of things. I like to put bulk things like beans, rice, sugar, flour, noodles, etc in food grade 5 gallon buckets with screw-on Gamma lids. You can vacuum seal it with O2 absorbers if you want, just not sugar! The trick is you need a way to cook it. If you have gas appliances you are most of the way there. Electric appliances, then you need alternatives. An important thing to remember is that you need a plan for what you are going to make, so you can make sure you have all the ingredients! Below are a couple of links. The 1st one is extensive information about how to store all kinds of foods. The 2nd one has some basic recipes. Enjoy, Resident Prepper signing off.
