I have helped with home canning many a time. It was a seasonal chore growing up. At my library, I am seeing a lot more interest in gardening and food preservation based on what is being checked out, so I think a lot of people have been responding to COVID lockdowns and inflation by returning to those skills.
Seasonal chore here as well, not just the canning, but the corn shucking, bean snapping, strawberry capping, pea splitting, and potato plucking that came before the canning. I suppose what we thought of as "old folks" back then really knew something after all. And the cycle continues.
