Why it works: Parsley and pepper 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 ↓
Baked Bluefish
Ingredients
Directions
The book says “a good oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the fish
Wash the bluefish thoroughly, removing any slime or dark tissue inside. Dry the fish.
Stuff the fish with veal stuffing. Sew the fish up.
Place the fish in a dripping pan and top with butter pieces. Sprinkle the fish with salt. Dredge the fish with flour.
Bake and make the sauce
Bake the fish at 400°F (200°C) for 30 to 40 minutes, depending on size.
While the fish is baking, chop the pickled cucumber or capers and parsley.
Once cooked, keep the fish hot and set the dripping pan on the stove.
Add flour to the pan and let it brown, stirring it into the butter and gravy.
Quickly pour in boiling water and claret wine, stirring until smooth.
Strain the sauce and mix in Worcestershire sauce, anchovy sauce, and the chopped pickles and parsley.
Serve
Serve the sauce separately, garnishing the fish with lemon points and parsley.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Bluefish
- Forms the main body of the dish, cooking through in the oven while the butter and pan juices develop.
- Butter
- Adds fat and richness, basting the fish as it bakes and enriching the pan gravy.
- Flour
- Thickens the pan juices into a gravy, and browning it deepens the flavour of the sauce.
- Pickled cucumber or capers
- Adds sharp acidity and salty brightness that cuts through the rich butter and gravy.
- Worcestershire sauce
- Adds savoury depth and a tangy, fermented note to the sauce.
- Anchovy sauce
- Adds a salty, savoury umami note to the sauce.
The step that matters
Browning the flour in the pan. Flour must be stirred into the butter and juices and browned before liquid is added, so it cooks out its raw taste and thickens smoothly. Adding the boiling liquid quickly, while stirring, prevents lumps from forming.
Swap the cucumber
How well each one fits the dish's main ingredients (bluefish, butter, flour, parsley, wine, pepper, sauce):

Fit is the average pairing score against bluefish, butter, flour, parsley, wine, pepper, sauce. Candidates are from the same food group and used in at least 100 recipes.
