Why it works: Bread and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 27,232 recipes. Both carry delta-decalactone, which smells sweet, creamy. The science ↓
To Make a Strong Fish Gravy
Ingredients
Directions
Prepare the fish
Skin, scale, gut, and wash the fish, then cut into small pieces.
Place the fish in a saucepan and cover with water.
Make the stock
Add the toasted bread, mace, whole peppercorns, sweet herbs, and lemon peel.
Boil until the mixture is rich and flavorful.
Make the gravy
Melt the butter in a separate saucepan.
Add flour to the melted butter and stir until browned.
Strain the fish gravy into the butter mixture and boil for a few minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eels or fish
- Provides the main flavor and body of the gravy as it simmers in the water.
- Butter
- Carries the flour and adds richness and a rounded flavor to the gravy.
- Flour
- Thickens the gravy and, when browned, adds a nutty, toasted flavor.
- Toasted bread
- Adds body and a toasted aroma to the stock.
The step that matters
Stirring the flour until browned. Flour cooked in fat must be stirred constantly so it browns evenly without scorching, which gives color and flavor. Scorched flour turns bitter and can ruin the gravy.
Swap the mace
How well each one fits the dish's main ingredients (fish, bread, lemon, butter, flour):
- Capersfits better
- Parsleyfits better
- Marjoramfits better
- Macethe original
Fit is the average pairing score against fish, bread, lemon, butter, flour. Candidates are from the same food group and used in at least 100 recipes.
