How to Cure Fish or Meat at Home

Fundamentals of curing

Salt dehydrates the surface and alters protein structure, inhibiting bacteria and creating firm textures and intense flavors. Sugar balances salt and adds softness.

Curing does not cook with heat: it is slow cold chemical transformation. Refrigeration is mandatory throughout the home process.

• Salt: dehydrates and inhibits bacteria.
• Sugar: balances and softens flavor.
• Always refrigerate during the process.

Wet and dry curing

In wet curing — like gravlax — salt and sugar form a mix that coats fish in a bag or wrap. In dry curing — pancetta, duck prosciutto — the mix is rubbed and the food hangs or rests in the fridge losing moisture.

Usual ratio for fish: 50% salt and 50% sugar by weight, plus dill or pepper. For thick meats, more salt and more time.

Reference times

Thickness determines duration. Weigh food before and after to monitor moisture loss.

In long cures, turn or massage the mix once a day for even salt and to avoid overly salty spots.

• Salmon gravlax (2 cm fillet): 24–36 hours in the refrigerator.
• Cured yolk: buried in salt and sugar, 4–7 days.
• Cured pancetta: 7–14 days, then dry 1–2 weeks.
• Cured duck breast: 24–48 hours, then dry.

Safety and consumption

Use very fresh fish or previously frozen according to local guidelines for parasites. Work with clean hands and utensils; discard used curing mix.

After curing, rinse lightly or brush off excess salt. Slice thinly. Store refrigerated wrapped: gravlax lasts 3–5 days; cured meats several weeks if moisture is low.
