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 ↓
Stewed Halibut
Ingredients
Directions
Poach the fish
Wash the fish.
Place the fish in a saucepan, barely covering it with warm water. Cover the saucepan with a lid.
Simmer slowly for 10 to 15 minutes, or place in a pie dish covered with a plate and stew in the oven.
Remove the fish to a plate.
Make the sauce
Blend the flour smoothly with a little milk.
Pour the mixture into the cooking water, stirring until it boils.
Add the parsley, salt, pepper, lemon juice, and remaining milk.
Return the fish to the sauce for 5 minutes to warm it.
Serve
Serve on a hot dish with the sauce poured over it.

Milk and flour barely smell alike, yet cooks put them together in 78,219 recipes: they work on texture and structure more than aroma.
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, cooking gently in warm water until flaky.
- Flour
- Thickens the cooking liquid into a smooth sauce as it heats and boils.
- Milk
- Adds creaminess and moisture to the sauce, softening its flavor.
- Lemon juice
- Adds acidity that brightens the mild fish and sauce.
The step that matters
Stirring the flour mixture into the water. Flour clumps if added without first being blended smooth with milk. Stirring while it comes to a boil lets the starch disperse and thicken the sauce evenly.
Swap the parsley
How well each one fits the dish's main ingredients (milk, flour, pepper, lemon):
- Cardamomfits better
- Marjoramfits about as well
- Parsleythe original
- Turmericfits about as well
Fit is the average pairing score against milk, flour, pepper, lemon. Candidates are from the same food group and used in at least 100 recipes.
