Why it works: Vinegar and fennel work together. They rank in the top 19% of all ingredient pairs, and cooks put them together in 505 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Pickle Salmon
Ingredients
Directions
Prepare the brine
Clean the fish without scraping off the scales and cut it into pieces about eight inches long.
Make a strong brine by mixing 2 pounds of coarse sea salt with 2 quarts of water and ¼ pint of vinegar.
Boil the brine slowly, just enough to cook the fish as you would for eating hot.
Drain the brine and let it cool.
Pickle and serve
Pack the fish pieces tightly in a kit or small tub.
Fill the tub with equal parts of best vinegar and the cooled brine.
Let it sit for a day or two, then refill as needed.
Serve with a garnish of fresh fennel.

What each ingredient does
- Coarse sea salt
- Draws water out of the fish and seasons it, helping preserve the flesh in the brine.
- Vinegar
- Adds acidity to the brine and filling, helping to preserve and sharpen the flavour of the fish.
- Best vinegar
- Makes up half the filling, giving the fish its main sour, pickled flavour.
The step that matters
Boil the brine slowly. Boiling only gently cooks the fish through without breaking up its flesh. Too vigorous a boil can toughen or fall apart the pieces.
