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 ↓
Bluefish a L’ltalienne
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the fish
Preheat the oven to 350°F (175°C).
Place the bluefish in a buttered pan.
Add white wine, mushroom liquor, onion, and mushrooms.
Season with salt and pepper.
Bake
Cover the fish with buttered paper and cook for 15 minutes.
Remove the fish and place it on a serving dish.
Make the sauce and serve
In a stewpan, combine the cooking juice, Espagnole sauce, and white wine.
Reduce for 2 minutes, then pour over the fish.
Garnish with parsley and serve with croutons.

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, cooked gently until it flakes.
- Espagnole sauce
- Gives the sauce body and a rich, savoury depth.
- White wine
- Adds acidity and aroma, and helps flavour the cooking liquid.
- Mushrooms
- Add earthy flavour and moisture to the cooking liquid.
- Mushroom liquor
- Adds concentrated mushroom flavour and moisture to the fish.
The step that matters
Reduce for 2 minutes, then pour over the fish. Reducing concentrates the cooking juices and sauce, so they thicken and taste rich rather than thin. Reducing too long can make the sauce salty and overly thick, so watch it closely.
Swap the onion
How well each one fits the dish's main ingredients (bluefish, white wine, mushroom, pepper, sauce, parsley):

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