Why it works: Celery and lemon match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and 3,467 recipes mention both. Both carry beta-phellandrene, which smells minty, terpene. The science ↓
The recipe
Ingredients
Contains: milk (auto-detected from the ingredients and method; we can miss things, so check labels)
Directions
Prepare the stock
Prepare the stock from veal or mutton bones for a white soup.
If no vegetables were boiled in the stock, simmer an onion or leek, a slice of turnip, and a small piece of celery in the stock for 20 minutes, then strain.
Make the soup
Melt the butter in a stewpan. Stir in the cornflour.
Pour in the milk and stock. Stir until the mixture boils.
Boil the macaroni in salted water for 20 minutes. Strain the macaroni and cut into 1-inch pieces.
Add the macaroni to the soup and simmer for 10 minutes.
Season the soup with salt, a dust of white pepper, and a few drops of lemon juice before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Macaroni
- Provides body and bulk, becoming tender as it simmers in the soup.
- Butter
- Forms the base with the cornflour, adding richness and a smooth mouthfeel.
- Cornflour
- Thickens the soup as it heats, giving it a smooth, velvety body.
- Milk
- Adds creaminess and a mild sweetness that makes the soup white and mellow.
- Bone stock
- Forms the main liquid and carries the savoury flavour of the soup.
The step that matters
Stirring the cornflour into the butter and adding the liquid. Cornflour must be cooked in fat and then brought to the boil with the liquid so its starch swells and thickens evenly; adding it lumpy or without boiling leaves the soup grainy and thin.
Flavor stand-ins for the onion
The recipe marks onion as optional. How well each one fits the dish's main ingredients (milk, butter, turnip, celery, white pepper, lemon):

Fit is the average pairing score against milk, butter, turnip, celery, white pepper, lemon. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
“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.
