You will find that the amish can a lot of their food. This is the main way of preserving their food for the year. This gives their food a distinquishable taste. It also helps with faster preperation of meals.
The food that I was not used to being canned was meat. I know you can buy canned meats, but is was not something I would hardly buy, except for tuna fish. It is actually pretty good, and you should try it.
This is also a reason why some foods may tast different after you take it home. Have a great day.
