What each ingredient does
- Mackerel
- The main fish, which firms when cooked and soaks up the pickling liquid.
- Vinegar
- Adds acidity that sharpens the flavor and helps preserve the fish.
- Black pepper
- Adds a sharp, pungent aroma to the pickling liquid.
- Bay leaves
- Adds a herbal, aromatic background note to the liquid.
The step that matters
Letting the fish stand covered for 24 hours. The acid and flavors need time to penetrate the flesh. Covering tightly keeps the aroma in and the fish evenly coated, so resting it short changes both flavor and texture.
