Why it works: Parsley and lemon 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 Fish
Ingredients
Directions
Prepare
Weigh the fish and bind it in thin muslin or cheese-cloth.
Fill a large kettle with water and add coarse sea salt to taste.
Poach the fish
Bring the water to a boil, then reduce heat slightly before adding the fish.
For large fish, add 3 tablespoons of vinegar to the water.
Keep the water boiling and cook for 6 minutes per pound, plus an additional 6 minutes for large fish.
Avoid piercing the fish to check doneness; ensure the water remains at a steady boil.
If the water boils too vigorously, move the kettle to a cooler part of the stove.
Serve
Serve the fish with drawn butter, sliced hard-boiled eggs, parsley, and sliced lemons. Optionally, add tomato ketchup.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fish
- Is the main dish, cooked whole so it holds its shape in the water.
- Vinegar
- Added to the water for large fish, it helps the flesh hold together during cooking.
The step that matters
Keep the water at a steady boil. If the water boils too hard, the fish can break apart and cook unevenly, while a drop in heat lets the water cool and the fish cook slowly. Avoid piercing the fish, since that lets juices escape and the flesh dry out.
Swap the tomato
The recipe marks tomato as optional. How well each one fits the dish's main ingredients (fish, cheese, vinegar, butter, egg, parsley, lemon):
- Shallotfits better
- Asparagusfits better
- Chivefits better
- Tomatothe original
Fit is the average pairing score against fish, cheese, vinegar, butter, egg, parsley, lemon. Candidates are from the same food group and used in at least 100 recipes.
