Why it works: White pepper and coriander work together. They rank in the top 19% of all ingredient pairs, and cooks put them together in 146 recipes. Both carry eucalyptol, which smells eucalyptus, herbal. The science ↓
Pickled Mackerel
Ingredients
Directions
Prepare the fish
Remove the heads and part of the skin from the belly of the mackerel.
Soak the fish in brine for 3 to 4 hours.
Cure and pack

Sprinkle some of the mixture on the bottom of a jar.
Layer the mackerel in the jar with the back side down.
Repeat layering with the remaining mixture and mackerel.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mackerel
- Is the main protein that the cure firms and preserves.
- Saltpetre
- Helps preserve the fish and keeps its color during curing.
- Coarse sea salt
- Draws out moisture and seasons the fish during the cure.
- Sugar
- Balances the saltiness and softens the harsh edge of the cure.
The step that matters
Layering the mackerel in the jar. Salt cure must reach every part of the fish evenly; packing the mixture between layers and keeping the fish submerged in its own brine prevents spoilage and uneven curing.
Swap the white pepper
How well each one fits the dish's main ingredients (sugar, coriander):

Fit is the average pairing score against sugar, coriander. Candidates are from the same food group and used in at least 100 recipes.
