Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fresh cod
- Forms the main protein, cooked gently in salted water until flaky.
- Vinegar
- Adds acidity during the soak, brightening the mild flavour of the fish.
- Coarse sea salt
- Seasons the cod and the poaching water.
The step that matters
Add the cod to the boiling water and cook for 10 minutes. Once the water is at a rolling boil, cod cooks quickly and can turn dry and tough if left too long. Timing the 10 minutes and removing the fish promptly keeps the flesh moist and tender.
Swap the lemon
How well each one fits the dish's main ingredients (vinegar, parsley, horseradish, shrimp, sauce, oyster):
- Limefits about as well
- Lemonthe original
- Avocadofits about as well
- Cherryfits less well
Fit is the average pairing score against vinegar, parsley, horseradish, shrimp, sauce, oyster. Candidates are from the same food group and used in at least 100 recipes.
