Why it works: Butter and flour 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 ↓
Halibut Steak
Ingredients
Directions
Prepare the fish
Sprinkle halibut steaks with coarse sea salt and white pepper.
Beat the egg with cold water in a saucer and dip the steaks in the mixture.
Coat the steaks well with flour.
Cook and serve
Heat the butter in a skillet over moderate heat until smoking hot.
Cook the steaks in the skillet, ensuring the heat is not too fierce to avoid scorching.
Serve with sliced lemon.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Halibut steaks
- The main fish, which firms and turns opaque as it cooks.
- Egg
- Binds the flour coating to the fish and helps it brown evenly in the pan.
- Flour
- Forms a dry coating that browns and crisps in the hot butter.
- Butter
- Conducts heat to the coating and adds richness and browning flavor.
The step that matters
Keeping the skillet heat moderate. Butter that is smoking hot can burn before the fish cooks through, and flour coatings scorch quickly at high heat. Moderate heat lets the coating brown evenly while the interior cooks gently.
Swap the white pepper
How well each one fits the dish's main ingredients (egg, butter, flour, lemon):
- Parsleyfits better
- Capersfits better
- Nutmegfits better
- White pepperthe original
Fit is the average pairing score against egg, butter, flour, lemon. Candidates are from the same food group and used in at least 100 recipes.
