Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- John dory fish
- The main protein; gentle simmering cooks its flesh until it turns opaque and flakes.
- Coarse sea salt
- Seasons the poaching water so the fish is flavoured as it cooks.
The step that matters
Bring the water to a boil gradually. Heating the cold water slowly and then simmering gently keeps the fish tender and intact. A hard, rapid boil can toughen the flesh and break it apart.
Swap the parsley
How well each one fits the dish's main ingredients (fish, lemon):
- Parsleythe original
- Tarragonfits about as well
- Marjoramfits less well
- Thymefits less well
Fit is the average pairing score against fish, lemon. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
