Kosher Salt for Canning Tomatoesの要点を丁寧に掘り下げてご紹介します。

Salt is the enemy of bad bacteria in canning. It draws out moisture. That moisture creates a brine that’s too salty for microbes to party in. Boom. Safe tomatoes.

But here’s the kicker: salt is not required for safety. Wait, what? Yes. You can can tomatoes with zero salt. The acid in tomatoes (plus proper heat) does the safety work. Salt is for flavor and texture.

Without salt, your tomatoes can taste flat. They might also get mushy. Salt firms up the pectin in the cell walls. It keeps your tomatoes from turning into sad, watery goo. Kosher salt saves your dinner.

A Warning About “Canning Salt”

You might see “canning salt” at the store. It’s basically super-fine kosher salt. It’s not better. It’s just more expensive. Don’t fall for the marketing. Your kosher salt is already perfect.

Canning salt can also clump in humidity. Kosher salt’s jagged flakes resist clumping better. You can even grind it between your fingers. That’s a tactile joy you don’t get with plain table salt.
