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 ↓
Clear Julienne Soup
Ingredients
Directions
Make the stock
Strain the clam liquor into a saucepan.
Add boiling water, onion, hard parts of the clams, salt, and pepper.
Simmer gently for 5 minutes, then strain.
Finish the soup
Melt the butter in a separate pot, stir in the flour.
Add the clam stock and milk, and bring to a boil.
Season to taste, then simmer gently for 5 minutes to cook the flour.
Add the soft parts of the clams and parsley, and serve immediately with crackers and pickles.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Thickens the butter and milk into a light, smooth body as it cooks.
- Butter
- Carries the flour and adds richness to the soup base.
- Milk
- Adds creaminess and a soft, mellow body to the broth.
- Clam liquor
- Provides the main clam flavour for the stock.
- Soft parts of clams
- Add the tender clam meat and its briny flavour at the end.
The step that matters
Simmer the flour after adding the milk. Flour thickens only when it is cooked long enough to swell and lose its raw taste. Simmering gently for the full 5 minutes cooks out the starchy flavour without scorching the milk, which can stick and burn if the heat is too high.
