Why it works: Parsley and pepper 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 ↓
Clam Soup
Ingredients
Directions
Prepare
Chop the clams very fine and drain them in a colander.
Chop the potatoes finely and boil them with the milk in a double boiler.
Rub the flour and butter together until creamy.
Make the soup
After the milk and potatoes have boiled for 15 minutes, stir in the flour and butter mixture and cook for 8 more minutes.
Add the parsley, salt, pepper, and the heated, skimmed clam liquor, then cook for 3 more minutes.
Finally, add the clams and 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 flavor and texture of the soup.
- Milk
- Forms the creamy liquid base of the soup.
- Potatoes
- Soften during cooking and thicken the soup body.
- Flour
- Thickens the milk when cooked with butter into a roux.
- Butter
- Adds richness and fat, and combines with flour to thicken.
The step that matters
Stirring in the flour and butter mixture. Lumps can form if the flour and butter are added to hot milk without being fully blended first. Cooking the mixture for a few minutes after adding it removes the raw flour taste and allows the soup to thicken evenly.
