Preservation

Every August, the same thing happens. The garden — or the farmer’s market, or the neighbor with the overproducing Roma plants — delivers more tomatoes than anyone can eat fresh. You know you should preserve them. But you don’t own a pressure canner, you’re not sure you want to buy one, and you’ve heard enough botulism horror stories to be nervous about doing it wrong.

There’s a moment every home canner remembers: the first ping of a lid sealing shut. It’s a small sound, but it means something big — you just preserved food that will still be good in a year, without a freezer, without electricity, without a single preservative.

If you’ve spent any time reading about home canning, you’ve run into the same fork in the road: water bath or pressure canning?

Most beginners pick one and hope for the best. That’s a mistake — not because one method is “better,” but because the two methods are not interchangeable. They exist for different reasons, and using the wrong one can turn a shelf of beautiful jars into a batch of spoiled food.
