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 ↓
Salt Mackerel with Cream Sauce
Ingredients
Directions
Prepare the fish
Soak the mackerel overnight in lukewarm water.
Change the water to ice‑cold in the morning.
Remove all the salt from the fish.
Wipe the fish dry.
Grease a grill with butter.
Rub the fish on both sides with melted butter.
Broil and keep warm
Broil the fish quickly over a clear fire, turning gently with a cake turner.
Place the fish on a hot‑water dish.
Cover the fish until the sauce is ready.
Make the cream sauce
Heat the milk until scalding.
Stir in the corn starch mixed with a little water until thickened.
Add the butter, pepper, salt, and chopped parsley to the thickened mixture.
Beat an egg lightly.
Gradually pour the sauce over the egg, stirring for one minute over low heat.
Serve

Keep the fish covered over hot water until serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Salt mackerel
- Is the main fish, softened by soaking to remove its salt before cooking.
- Milk
- Forms the liquid base of the cream sauce.
- Corn starch
- Thickens the milk into a smooth sauce as it heats.
- Butter
- Adds richness and flavour to the sauce and browns the fish surface.
The step that matters
Gradually pour the sauce over the egg. Adding hot sauce slowly while stirring tempers the egg so it thickens smoothly instead of scrambling. Keeping the heat low prevents curdling.
Swap the parsley
How well each one fits the dish's main ingredients (milk, corn, butter, pepper):
- Cinnamonfits better
- Nutmegfits about as well
- Parsleythe original
- Thymefits about as well
Fit is the average pairing score against milk, corn, butter, pepper. Candidates are from the same food group and used in at least 100 recipes.
