Why it works: Flour and butter are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Fried Bluefish
Ingredients
Directions
Prepare
Clean the bluefish and wipe it dry inside and out.
Sprinkle the fish well with flour and season with a good pinch of coarse sea salt.
Fry and serve
Heat enough butter or sweet lard in a skillet so the fish won't stick.
Fry the fish until golden brown.
Remove the fish and drain in a hot strainer.
Garnish with parsley and serve in a heated dish.

Flour and butter 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
- The main ingredient, which becomes flaky and cooked through in the hot fat.
- Flour
- Forms a coating that crisps and browns in the hot fat, sealing in moisture.
- Butter or sweet lard
- Fat for frying that conducts heat evenly and browns the flour coating.
The step that matters
Heat the fat before frying. The fat must be hot enough to sear the floured coating quickly. A quick sear forms a crust that releases from the skillet, while cool fat lets the coating stick and soak up grease.
