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 ↓

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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
- Butter
- Adds fat and flavour, and helps the fillets brown in the pan.
- Flour
- Forms a light coating that helps the surface brown and crisp.
- Haddock fillets
- The main protein, which cooks through and turns flaky as it heats.
The step that matters
Flip the fillets halfway through cooking. Turning the fillets exposes both sides to the pan's heat, so they cook evenly and brown on both faces instead of leaving one side pale or undercooked.
“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.
