Why it works: Pepper and parsley match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Purie of Clams
Ingredients
Directions
Prepare the clams
If using raw clams, simmer them in white stock for 1 hour; if using canned clams, simmer for 15 minutes.
Rub the clams through a sieve until only the hard parts remain.
Make the soup
Fry the onion in butter, then add flour and mix well.
Pour in the clam liquor and add salt, pepper, parsley, and mace.
Cook for 10 minutes, then dilute with milk.
Slowly add the beaten egg yolks to the soup to avoid coagulation, then serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Clams
- Provide the main flavour and body of the purée once rubbed through a sieve.
- Butter
- Carries the frying of the onion and adds richness to the soup.
- Flour
- Cooked with the butter to form a roux that thickens the soup.
- Milk
- Dilutes the soup and adds creaminess and softness to the purée.
- Egg yolks
- Enrich and thicken the soup, adding body and a smooth, velvety texture.
The step that matters
Adding the egg yolks. Egg yolks thicken by coagulating when heated, so curdling is likely if they meet hot soup too quickly. Adding them slowly, with the soup off the boil, lets them blend in and thicken it smoothly.
Swap the mace
How well each one fits the dish's main ingredients (clam, onion, butter, flour, pepper, parsley, milk):
