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 and bake
Clean the bluefish thoroughly, removing any slime or dark matter inside. Then use your finger and some salt to clean the inside, and wipe it dry.
Stuff the fish with veal stuffing and sew it up.
Place it in a dripping pan. Dot the fish with butter pieces, sprinkle with salt, and dredge with flour.
Bake in a 400°F (200°C) oven 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.
Make the sauce
Place the dripping pan on the stove. Add 2 teaspoons of flour to the pan and let it brown, stirring with a spoon.
Pour in the boiling water and claret wine (if using). Season with pepper and stir until smooth.
Strain the sauce.
Mix in Worcestershire sauce, anchovy sauce, and the chopped pickles and parsley.
Serve
Serve the sauce separately, garnished with lemon points and parsley.

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
- Bluefish
- Forms the main body of the dish, cooking through in the oven to become flaky.
- Butter
- Adds moisture and richness as it melts over the fish during baking.
- Flour
- Browns in the pan and thickens the sauce as it cooks with the liquid.
- Pickled cucumber or capers
- Adds acidity and a briny bite that cuts through the richness of the sauce.
- Worcestershire sauce
- Adds savoury depth and a tangy, fermented sharpness to the sauce.
- Anchovy sauce
- Adds salty, savoury depth that rounds out the flavour of the sauce.
The step that matters
Browning the flour before adding liquid. Stirring the flour in the hot pan until it browns cooks out its raw taste and helps prevent lumps. Adding the boiling water too early can leave the sauce floury and dull in flavour.
Swap the cucumber
