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
- Chicken livers (in the method)
- Provide the main protein, which browns on the surface while staying tender inside.
- Madeira
- Adds sweetness and aroma, and its liquid lifts browned bits from the pan into the sauce.
- Brown sauce
- Supplies savory depth and body, thickening the liquid as it simmers with the livers.
- Butter
- Carries heat for browning and adds richness and a nutty aroma.
- Flour
- Dries the liver surface and helps it brown and thicken the pan liquid.
The step that matters
Brown the livers in butter. The livers must be dry and the pan hot enough to brown them. Wet or crowded livers steam instead of browning, which loses the deep flavor the sauce depends on.
