Draw moisture out of food with salt to create an environment where harmful bacteria cannot thrive.
Weigh food and salt precisely — most cures use 2–3% salt by weight for equilibrium curing.
Rub salt (and sugar/spices if using) evenly over all surfaces.
Place in a non-reactive container and refrigerate for the cure duration.
Rinse or pat dry as directed, then air-dry or cook before serving.
For dry-cured items, hang in a cool, humid-controlled environment until firm.
Weeks to months refrigerated depending on cure; salt cod can last a year dried
