Multiply perishable items, such as milk or eggs, depending on what your household normally uses. The World Health Organization recommends 2,100 calories from food per day. This is what an average person doing a light activity would need. The general rule for disaster scenarios is a minimum of 2 weeks of non-perishable food.
There are people who passionately argue that you need 6 months, 12 months or even 2 years of food on hand. To survive 2 weeks, a family of 4 needs 112,000 calories and 56 gallons of water. Therefore, the first goal of crouching food storage is simply to allow you and your family to continue eating despite an interruption in the normal food delivery system, without standing on a FEMA or Red Cross line for 8 hours a day. Certainly, if you live in a warm climate, having an outdoor grill or solar oven can make cooking food easier.
But even though most non-perishable non-perishable non-perishable foods may be safe to eat well beyond their best-buy or best before date, it would make sense for them to lose some of their nutritional value over time. It depends on your situation, but from my point of view, lentils and white rice seem like a great addition to a food reserve. The garage is a good location if you live in a mild climate, but if you live in a place like Texas or Florida, heat buildup in the garage can shorten the lifespan of even well-packaged emergency food. Stored warm water can also be useful when you want to heat some foods in a pan or saucepan on the trivet to help reduce heating time.
A cast iron trivet with a tea candle can provide a surprising amount of heat for heating canned food and heating water for instant tea or coffee. Don't forget to consider any special dietary needs, such as allergies or diabetes, when making your 2-week food list. When the power goes out, you should focus on eating as many perishable foods as possible and keeping them, if you know how. That said, I wouldn't want to eat Mountain House Pasta Primavera long term after a disaster, so I think rebuilding a good pantry would be helpful and might even help with my current problems getting a decent meal on the table with my limited time.
The goal might be survival, but storing food that you never eat or enjoy will make a difficult situation even more difficult for your family. Sorry, I should have thanked you for the excellent post on the two-week supply before commenting on the concern about egg storage.
