What each ingredient does

String beans
The main vegetable, providing the bulk and firm-tender texture of the finished canned beans.
Water
Fills the cans around the beans, carrying the salt and conducting heat during the long process.

The step that matters

Boil the sealed cans in a hot water bath. The sealed cans must be heated long enough for the heat to reach the beans throughout. This long heat treatment kills microorganisms and softens the beans, so a shorter or cooler process can leave a spoilage risk.
