Why it works: Pepper and parsley match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Red Mullet Baked
Ingredients
Directions
The book gives no oven temperature. The 300°F (150°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the fish
Clean the fish as you would for grey mullet.
Score the fish.
Fold the fish in oiled or buttered paper.
Bake and make the sauce
Bake in a slow oven at 300°F (150°C) for about fifteen minutes.
Pour the cooking liquid into a saucepan with 1 ounce of butter.
Thicken the sauce with flour.
Season with coarse sea salt, a little cayenne, and chopped parsley.
Bring the sauce to a boil and serve in a tureen.

Butter and flour barely smell alike, yet cooks put them together in 124,287 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
- Red mullet
- The main fish, which becomes the dish's delicate, flaky centrepiece once baked.
- Butter
- Adds richness and a silky mouthfeel to the sauce made from the cooking liquid.
- Flour
- Thickens the cooking liquid so the sauce coats the fish instead of running thin.
The step that matters
Thicken the sauce with flour. Flour must be cooked into the butter and liquid, then brought to a boil, so it swells and thickens fully. If it is added raw or the sauce is not heated enough, it stays grainy and thin.
Swap the parsley
How well each one fits the dish's main ingredients (butter, flour, pepper):
- Parsleythe original
- Turmericfits about as well
- Nutmegfits about as well
- Sagefits less well
Fit is the average pairing score against butter, flour, pepper. Candidates are from the same food group and used in at least 100 recipes.
