Ball Blue Book Guide to Preserving

The book covers a wide range of techniques, but I'm curious how the selections were made—were they based on popularity, safety, or personal experience?

Some of the advice feels rooted in tradition, which I love, but I wonder if some methods are less relevant today or need modern tweaks.

The emphasis on self-sufficiency really resonated with me, but I’d love to know if the author’s own gardening and preserving journey influenced this focus.
