Why it works: Shallot and parsley match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 3,737 recipes. Both carry 2,4-decadienal, which smells seaweed. The science ↓
Calf's Liver À LA Bourgeoise
Ingredients
Directions
Make the sauce base
In a stewpan, combine the sliced calf's liver, shallot, parsley, green onions, and butter.
Cook over medium heat, shaking the pan occasionally, and sprinkle in the flour.
Add the water and white wine, then season with salt and coarse black pepper.
Bring to a boil and let simmer for 30 minutes.
Thicken and serve
In a bowl, beat the egg yolks with the vinegar.
When the liver is cooked and the sauce is nearly reduced, stir in the egg mixture to thicken the sauce.
Serve immediately.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Calf's liver
- Is the main protein, cooked gently in the sauce until tender.
- Butter
- Adds fat and richness, and helps the liver brown lightly in the pan.
- Flour
- Thickens the cooking liquid and helps form the sauce body.
- White wine
- Adds acidity and aroma that balance the rich liver and butter.
- Egg yolks
- Enrich and thicken the sauce as they set gently with heat.
The step that matters
Stirring in the egg yolk mixture. Egg yolks thicken by gentle heat, but if the sauce is too hot or boiling when they are added, the yolks can scramble and turn grainy. Remove from the heat or lower it before stirring in the mixture.
