How to Cure and Smoke Fish
Ingredients
Directions
Prepare
Scale and clean the fish by slitting it up the back.
Wipe the fish with a damp cloth; do not wash.
Cure
Mix the salt, brown sugar, and saltpetre together.
Rub the mixture inside and out of the fish.
Stack the fish with a board on top and place heavy weights to press them down.
Let them sit for 60 hours.
Smoke
Drain and wipe the fish dry.
Stretch the fish open and fasten with small sticks.
Smoke the fish for 5 days in a smokehouse or in a barrel over a smothered wood fire.

What each ingredient does
- Fish
- The main protein, which the salt cure penetrates and firms as it dries.
- Coarse sea salt
- Draws out moisture and seasons the fish, slowing spoilage during curing.
- Brown sugar
- Balances the saltiness and adds mild sweetness and flavour to the cured fish.
- Saltpetre
- Helps preserve the fish and keeps its colour during curing.
The step that matters
Drain and wipe the fish dry. A dry surface helps smoke adhere and form a glossy pellicle that slows spoilage. Leftover moisture and brine can cause uneven smoke colour and encourage microbial growth.
