When I got interested in preserving due to the necessity of throwing out most of what was available, I did a lot of experimenting and decided on pressure canning. Up to some deep experimenting, I accepted all the dogmas without hesitation, and then after much reflection decided on my present method.
I seriously looked at all methods, and utilized if suitable, but in general all were undesirable except for pressure canning. Some of the methods had niche advantages and uses. The methods considered were, drying, freezing, hot water bath preserving, lacto fermenting, grease preserving(pemmican) and pressure canning.
I developed the pressure canning method so it is almost as effortless as cooking a pot of material for a meal. If a preserving method is onerous it will not be seriously implemented.
One only has to look around to see that there is something seriously wrong with our eating habits.
The bottom line mantra is eat as much fresh as possible, then fall back on nutritional preserves.
How is that for preaching?
