Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Calf's liver
- Main protein that gives the dish its body and softens to tenderness as it stews.
- Bacon
- Adds fat and savoury, smoky flavour that carries into the stewing liquid.
- Butter
- Adds fat for richness and a smoother mouthfeel when stirred in at the end.
- Egg
- Its proteins set when heated, thickening the mixture.
The step that matters
Thickening with the egg. Egg proteins set when heated, so they thicken the sauce, but if the mixture is too hot or boiling, the egg can scramble into lumps. Stir steadily and add it once the liver is tender and the pan is no longer boiling.
