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 White Fish
Ingredients
Directions
Prepare
Wash the fish thoroughly with a little salt to remove any dark skin or blood.
Tie the fish into a good shape.
Place the fish on a drainer.
Poach
In a pan, bring enough water to a boil to cover the fish.
Remove the pan from heat.
Add 1 tablespoon of salt per quart of water and 1 tablespoon of vinegar.
Place the fish in the water and cook gently just below boiling point.
Cook for 6 minutes per pound, plus an additional 6 minutes, or 10 minutes per pound for a large cut.
Drain the fish.
Serve
Serve on a folded napkin.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- White fish
- Forms the main body of the dish, cooking gently to stay moist and flaky.
- Vinegar
- Adds a light acidity to the poaching water, brightening the mild flavour of the fish.
The step that matters
Cook gently just below boiling point. At a rolling boil the outside of the fish toughens and breaks apart before the centre cooks. Gentle, sub-boiling heat keeps the flesh tender, moist and intact.
Swap the parsley
How well each one fits the dish's main ingredients (fish, vinegar, lemon):
- Tarragonfits better
- Parsleythe original
- Dillfits about as well
- Marjoramfits about as well
Fit is the average pairing score against fish, vinegar, 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.
