How it works
Kimchi is a controlled ecosystem.
1 · Salt
Osmosis pulls water out and tightens pectin for crunch.
2 · Paste
Capsaicin, sulfur compounds and umami amino acids.
3 · Pack
Solids under brine give lacto-fermenters the advantage.
4 · Ferment
Lactic acid lowers pH for that tangy, preserved bite.
