Why it works: Fish and butter match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and 4,432 recipes mention both. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
The recipe
Ingredients
Contains: milk, wheat, soy, fish (auto-detected from the ingredients and method; we can miss things, so check labels)
Directions
Prepare
Clean the sounds and simmer them in water for 30 minutes.
Rub the sounds with butter and dredge with flour.
Season with coarse sea salt and white pepper.
Broil and serve
Place the sounds on a grill over a clear fire to broil for about 40 minutes.
In a saucepan, heat ½ cup of melted butter and mix in 1 teaspoon of mustard, 2 teaspoons of soy sauce, and a sprinkle of cayenne pepper.
Pour the heated sauce over the broiled sounds before serving.

Butter and flour share little aroma chemistry, yet 122,858 recipes mention both: they likely 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
- Sounds (fish)
- Forms the main flesh that is cooked and served as the dish.
- Butter
- Adds richness and moisture to the fish and carries the sauce.
- Flour
- Dredged onto the fish to help form a light coating that browns during broiling.
- Soy sauce
- Adds savoury depth and salt to the sauce, along with some browning.
The step that matters
Broiling the sounds over a clear fire for about 40 minutes. Fish flesh turns dry and tough when overcooked, and the heat must be steady enough to cook the centre without scorching the flour coating. Checking for flaking helps avoid overcooking.
Flavor stand-ins for the white pepper
How well each one fits the dish's main ingredients (fish, butter, flour, mustard, sauce, pepper):

- White pepperthe original
Fit is the average pairing score against fish, butter, flour, mustard, sauce, pepper. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
