Why it works: Flour and lemon are a kitchen classic. They rank in the top 17% of all ingredient pairs, and cooks put them together in 30,404 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
- Calf's liver
- Provides the main protein, cooked quickly so it stays tender inside.
- Flour
- Forms a thin coating that promotes browning and helps the surface crisp in the hot oil.
- Italian sauce
- Adds moisture and a rich, savoury finish to the cooked liver.
- Lemon juice
- Adds acidity that brightens the rich flavour of the liver and sauce.
The step that matters
Check doneness by cutting into a slice. Liver overcooks quickly and turns dry and grainy. Cutting a slice to check the centre lets the cook stop cooking while it is still tender and slightly pink inside.
