Salt level notes at 3.5%

Kimchi salting is a 2-stage process: 3.5-4% dry salt → 2-4 hour rest (flip halfway) → 3x rinse → paste application. The salt drawn into the water during rest is what rinses away. Final kimchi effective salt is ~2%.

Safety: Flavour-forward. Ferment will be slower; brine will taste salty. Good for pickles and hot-sauce mashes that need long shelf life.
