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 ↓
Salt Fish
Ingredients
Directions
Prepare the sauce
Remove the skin and bones from the fish and place it in a clean saucepan.
In a separate pan, melt the butter with water and flour over low heat.
Add pepper, salt, and minced parsley to the butter mixture.
Cook and serve
Heat the fish slowly in the sauce, stirring until well mixed.
Just before serving, add lemon juice or chili vinegar.
Serve the fish in a deep dish with a border of mashed parsnips or potatoes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fish
- Forms the main body of the dish, flaking into the sauce as it heats.
- Butter
- Provides fat and richness, carrying the flavour of the sauce.
- Flour
- Thickens the butter and water into a smooth, lightly bodied sauce.
- Lemon juice or chili vinegar
- Adds acidity that brightens the rich butter sauce just before serving.
The step that matters
Adding the lemon juice or chili vinegar. Acid added too early and heated for long can dull its brightness and make the sauce taste flat. Adding it just before serving keeps the flavour fresh and sharp.
Swap the parsnip
How well each one fits the dish's main ingredients (fish, butter, flour, pepper, parsley, lemon):
