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, providing its meaty texture and rich flavor.
- Butter
- Adds fat that gives richness and a smoother mouthfeel to the stewed liver.
- Flour
- Thickens the cooking liquid as its starch swells when heated with water.
The step that matters
Finish stewing the liver gently. Liver proteins tighten and turn grainy and tough when overcooked. Cooking it until just done, after the partial cook, keeps it tender and moist.
