Why it works: Parsley and celery match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 6,810 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Baked Fish
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the fish
Make about four slashes on each side of the fish and insert pieces of bacon.
Rub the fish with butter and dust with flour.
Bake
Place the fish in a pan and pour in boiling water, salt, and vinegar.
Bake at 400°F (200°C) for 40 minutes, basting often and adding more water if needed.
Make the sauce and serve
When done, remove the fish and make the sauce in the same pan.
Add flour, milk, and a little butter to the pan, stirring to combine.
Stir in chopped parsley, celery salt, and paprika.
Pour the sauce over the fish on the platter and serve.

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
- Bacon
- Adds salty, savoury fat that flavours the fish from within as it cooks.
- Flour
- Dusted on the fish and stirred into the sauce to thicken it and give body.
- Milk
- Combines with the flour and butter to form a creamy, thickened sauce.
- Butter
- Adds richness and fat that helps the fish brown and carries flavour into the sauce.
- Vinegar
- Adds a little acidity that brightens the fish and the sauce.
The step that matters
Basting during the bake. Fish is lean and dries out quickly in the oven. Basting with the liquid in the pan keeps the surface moist and the flesh tender, and adding water as it reduces prevents scorching and sticking.
Swap the celery
How well each one fits the dish's main ingredients (fish, butter, flour, vinegar, sauce, milk, parsley):
- Capersfits better
- Tarragonfits better
- Nutmegfits about as well
- Celerythe original
Fit is the average pairing score against fish, butter, flour, vinegar, sauce, milk, parsley. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
