Why it works: Onion and parsley are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 25,843 recipes. Both carry 2,4-decadienal, which smells seaweed. The science ↓

Ingredients
Directions
Make the broth
In a large pot, boil the water with veal, fowl, whole white pepper, mace, and onions for 3 hours.
Strain the soup and return it to the pot to heat.
Finish the soup
Just before serving, gradually stir in the cream mixed with the beaten egg yolks.
Do not let the soup boil after adding the cream and eggs to prevent curdling.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Veal
- Gives the broth its meaty body and rich flavour as it simmers.
- Egg yolks
- Thicken the soup gently and add richness when stirred in off the heat.
- Cream
- Adds fat and a smooth, silky texture to the finished soup.
The step that matters
Do not let the soup boil after adding the cream and eggs. Egg yolks coagulate and can curdle when overheated, leaving a grainy texture. Keeping the soup below a boil after they go in keeps it smooth and thickened.
