The variety of tinned and jarred food available these days is very wide; some of it is immediately edible, some is more usually used as an ingredient to add to other items (e.g. from the dried food list). Here are some starting points for you to consider.
- Tinned meat and tinned fish. The oil in which tinned fish is often produced can also be used to flavour other food.
- Tinned vegetables. Obviously there are many different options here. Some popular ones include: tomatoes (very versatile); beans of various kinds; potatoes; corn; lentils; carrots; peas; and various combinations of mixed vegetables.
- Tinned soup. Most of these do not absolutely require heating if the power is out!
- Tinned all-in-one meals: chili, beans with sausages, and so on. Again, many of these can be eaten cold if necessary.
- Tinned fruit. These days often in fruit juice rather than sugar syrup, which is at least slightly healthier! Consider also some tins of evaporated milk or condensed milk to go with this, or to use for other purposes.
- Preserved vegetables: for instance olives or sun-dried tomatoes. Possibly not ideal if you are tight on space, maybe not the cheapest either, but a nice change if you can justify them.
- Jam, honey and peanut butter. As well as a spread, honey can be used as a sweetener and is said to have antiseptic properties. Peanut butter is extremely high in energy.
