Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Calf's liver
- Forms the main body of the dish; frying gives it a browned exterior and a tender interior.
- Flour
- Coats the liver so it browns evenly and the surface crisps during frying.
- Gravy
- Provides moisture and savory depth as the liquid the liver stews in.
- Onions
- Add sweetness and aroma as they soften in the hot gravy.
- Wine
- Adds acidity and depth of flavor when stirred in at the end.
The step that matters
Frying the floured liver until light brown. Liver overcooks quickly and turns tough and dry if fried too long. Stopping at light browning keeps it tender, since it cooks further when it stews in the gravy.
Swap the onion
