Why it works: Lemon and parsley match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 14,037 recipes. Both carry beta-phellandrene, which smells minty, terpene. The science ↓
Boiled Halibut
Ingredients
Directions
In a large pot, bring enough water to a boil to cover the halibut.
Add salt and vinegar to the boiling water.
Carefully add the halibut and let the water return to a boil. Skim off any foam, then reduce heat and cook slowly for 25 minutes.
Serve the halibut on a hot napkin, garnished with lemon and parsley, alongside a fish sauce.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Halibut
- Forms the main body of the dish; gentle simmering cooks its flesh until it turns opaque and flakes.
- Vinegar
- Adds a light acidity that brightens the mild flavour of the fish.
- Fish sauce
- Adds a savoury, salty depth to the plain boiled fish when served alongside.
The step that matters
Skim off any foam, then reduce heat and cook slowly. Foam that forms as the water returns to a boil can cloud the broth and cling to the fish. Lowering the heat keeps the water at a gentle simmer, so the fish cooks evenly and stays tender rather than tightening and breaking apart.
Swap the lemon
How well each one fits the dish's main ingredients (vinegar, parsley, fish sauce):
- Limefits better
- Lemonthe original
- Mangofits less well
- Cherryfits less well
Fit is the average pairing score against vinegar, parsley, fish sauce. Candidates are from the same food group and used in at least 100 recipes.
