Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sheep's feet (trotters)
- Provide the gelatinous skin and connective tissue that give the stew its body and richness.
- Egg yolks
- Thicken the sauce as they set gently with heat, giving it a smooth, velvety texture.
- Lemon juice
- Adds acidity that brightens the rich sauce and balances its fat.
- Butter
- Adds fat that enriches the sauce and gives it a smooth, glossy finish.
The step that matters
Thicken the sauce with diluted egg yolks. Egg yolks can curdle or scramble if the sauce is too hot. Diluting them first and adding them off the boil lets them thicken smoothly.
