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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds richness and fat, and carries the flour into a smooth base.
- Flour
- Thickens the butter and liquor into a sauce that coats the cockles.
- Cockle liquor
- Adds the sea-based flavour that makes the sauce taste of cockles.
- Anchovy paste or small fish
- Adds savoury depth and salty, umami notes to the sauce.
- Vinegar
- Adds acidity that brightens the sauce and balances the richness of the butter.
- Cockles
- Provide the main shellfish flavour and chewy texture in the finished sauce.
The step that matters
Adding the cockles and shaking the pan. Cockles are shellfish, and proteins toughen quickly with heat. Adding them at the end and heating only briefly keeps them tender and stops them turning rubbery in the sauce.
