I have been storing firewood. I also have two camp stoves, a single burner and a double burner. When things first fall out, my intention is to use the wood in one or more rocket stoves to heat water. Hot water will be a necessity for sanitation, utensil washing and general hygiene. The camp stoves will be used for cooking. That will continue until the fuel is exhausted. By that time I hope to have gained enough experience that I will be able to modulate the wood burning rockets stoves so that cooking on them will not be that much of a problem. I also plan to use wood burning to distill water as I anticipate that we will need to use ocean water for our water supply unless we just happen to have a wet year such as we are experiencing this year. If it were last year, we definitely would be distilling ocean water. Ocean water doesn’t have to be distilled for washing utensils, hands and clothing. It must be boiled however because there will be all sorts of stuff floating in the ocean that you wouldn’t want to touch let along wash with. Drinking water and water for face washing and teeth brushing will have to be distilled as one cannot drink salt water. I would recommend dehydrated foods for getting used to outdoor cooking, but for long term food you are going to need beans and rice. You can store a lot of calories in a small space for a long time with those two items. Beans and rice together release the protein in the beans to supplement the meat you eat. I always wondered why Mexican food featured beans and rice at the same meal. I thought it was overkill on carbs. Then I found out that the rice released the protein in the beans which otherwise was locked and unavailable.
It’s impossible to carry all the food you will need for a week unless you’re eating very high density proteins like nuts.  Nuts and dried meat are two of the easiest off-the-cuff meals.  Canned food has a lot of water that is wasted during the cooking process.  Stay away from heavily flavored or salted nuts.  The amount of salt present in the unsalted nut mixes is still sufficient enough to replace electrolytes.
Rice. This is an old standby. It can form the base of many tasty and nutritious meals. Be aware that although it requires no processing, it does require quite a bit of water to cook. It is most economical to buy rice in 40 lb bags and repackage it into buckets yourself, a 5 gallon bucket will hold a 40lb bag. For a bit more you can find rice sold pre-sealed in buckets from a number of sources.
Cooking fats can be substituted in most cases with the exception being frying. Some oils and fats have a lower smoke point than others. I have never had any luck using olive oil for trying to fry potatoes to a crispy state but grape seed oil, peanut oil, or lard does just fine. Pie crusts made from lard, flour, salt, and a little water are really good. You really don’t need butter to make a flaky crust if you have lard.
In an end of the world situation, we won’t have to worry about too much salt or too much sugar. Our main concerns will be keeping warm, getting potable water and enough to eat. A steady diet of tuna fish, canned meats, pasta, bean and rice will quickly get old. You will be happy to have the sugary canned fruit which will add very necessary calories to your diet and provide energy. The high salt which is dangerous now will provide necessary salts when you have otherwise run out of salt for cooking. In addition, most of the prepared foods are prepared to appeal to our taste buds. Food companies spend big money on making “convenience”
I am officially embarrassed to be an American. My niece just told me she wants to be a prepper because she’s afraid for the future, and wanted some help getting started. I asked her what she wanted to prepare for, and you know what she said? “I’m afraid the president is going to get us killed with the things he says and does.”. I may not be a big fan of him, but that just embarrasses the hell out of me.
My dad was a USN Seabee, who’s unit moved into Nagasaki, after the blast. He thought that most people,would find the post blast world extremely traumatizing and physically demanding. His comment re 1960s Hydrogen bomb which has since been eclipsed a thousandfold at least. The article didn’t address dealing with a Neutron bomb, which is designed to leave infrastructure intact, but intended instead to penetrate such deeply, to create cell damage to living organisms.
Manufacturers make special kinds of heavy concrete that absorb more radiation, usually for nuclear waste storage facilities. But ultimately, you’ll need a very thick layer of concrete, not only for the walls but above and below you. It’s important to calculate how much radiation your bunker will need to absorb in the worst-case scenario you’re prepping for.
You can figure 25-30 years storage life for hard red wheat, stored at 60 degrees in a 55 gallon drum, using 1 pound of dry ice to drive out the oxygen (wait 24hrs for the dry ice to “melt” before sealing the drum). 400 pounds of wheat per drum equals 400 man-days of calories, and costs you about $100. Fill 3-4 barrels. It’s Cheap insurance. Add a barrel of Winter Rye for variety. Add a barrel of oats. Then a couple barrels of WHITE rice, and 2-3 barrels of pinto beans. (You need the beans to balance what’s missing from the grains. The beans may be harder to rehydrate after 10-12 years without a pressure cooker, but then you just grind up the dried beans, and bake them in your bread.) For around $1000, you can be prepared to feed your family for close to a decade, if you also garden, keep chickens, and have fruit trees and bushes. Honey is way too expensive to store on a dollar/calorie basis, but consider bee keeping. A drum takes up LESS than 2’X2’. And they stack nicely, at 33” tall. In a 2’X10′ strip along a basement wall, you can have 10 barrels with 4000 pounds of food. Hang a peg board in front of it, and you’ve got very useful space. If you can’t spare that much space in your basement, to protect the lives of your family, think Venezuela .
Disturbing news from the Southern Carribean.  The World Bank just “ruled” against Venezuela in favor of oil giant ConocoPhillips, saying they could “seize” their government owned oil assets.  All this while Russian nuclear bombers and naval vessels have been sighted in the area.  Venezuela, already on the verge of collapse, may be the next flash point in the world.  Lawsuit Article Link

Though its light weight and long shelf life are ideal for navigating harsh conditions, freeze-dried food is probably most famous as a cultural curiosity: Like many Americans, I discovered it in a museum gift shop, gawking at the styrofoam-like ice cream that astronauts used to have for dessert. More recently, I encountered it at a disaster preparedness convention in Raleigh, North Carolina, where smiling, gray-haired preppers manned tables piled with plastic bags full of vegetables, meats, and stews.
