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 ↓

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
- Shad roes
- Provide the main flavour and body of the sauce once mashed into it.
- Butter
- Melts with the flour to form the base of the white sauce and adds richness.
- Flour
- Thickens the butter and liquid into a white sauce that carries the roe.
The step that matters
Simmer the roe gently. Boiling roe rapidly can toughen its delicate protein and make it grainy, so keeping the water at a gentle simmer keeps it tender before mashing.
