Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Clam Soup
Ingredients
Directions
Prepare the clams
Strain the liquid from the clams and chop them finely.
Make the soup
In a porcelain kettle, combine the clams and boiling water; let it boil slowly for 2 hours.
Cream the butter and flour together, then add to the kettle and let it boil once.
Season with pepper and coarse sea salt to taste.
Finish with the egg and milk
In a separate bowl, beat the egg yolks and mix with the fresh milk.
Remove the soup from heat and stir in the egg and milk mixture. Do not boil after adding.

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 soup, releasing their savoury liquor as they cook.
- Butter and flour
- Creamed together and boiled in, they thicken the soup slightly.
- Egg yolks
- Enrich the soup and give it a smooth, creamy texture when stirred in off the heat.
- Fresh milk
- Adds richness and creaminess, mellowing the broth.
The step that matters
Adding the egg and milk mixture off the heat. Egg yolks thicken and can curdle or scramble if they get too hot. Removing the soup from heat before stirring in the mixture, and not boiling afterward, keeps it smooth.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
