Why it works: Carrot and parsley match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and 8,053 recipes mention both. Both carry 2,4-decadienal, which smells seaweed. The science ↓
Palestine Soup
Ingredients
Directions
Prepare
Peel and chop the carrot and potatoes.
In a stewpan, combine the carrot, potatoes, butter, ham, and parsley.
Cook over high heat for 10 minutes.
Stir in the flour until well mixed.
Make the soup
Add the stock and boiling milk, stirring until boiling.
Season with salt and sugar.
Rub the mixture through a sieve into another stewpan.
Bring to a boil again, skim, and serve with croutons.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Break down when rubbed through the sieve, giving the soup body and a thick texture.
- Butter
- Adds fat for richness and a smooth mouthfeel in the finished soup.
- Flour
- Thickens the soup as it heats with the stock and milk, giving it body.
- Lean ham
- Provides savory, salty meat flavor that carries through the soup.
- Milk
- Adds creaminess and mild sweetness, softening the savory stock flavor.
The step that matters
Stir in the flour until well mixed. Flour clumps if added to hot liquid without being evenly mixed into the vegetables and fat first. Thorough mixing lets it dissolve and thicken the soup smoothly when the stock and milk are added.
Flavor stand-ins for the parsley
How well each one fits the dish's main ingredients (carrot, potato, butter, ham, flour, milk, sugar):
- Cinnamonbetter flavor fit

- Parsleythe original
- Celeryabout as good a flavor fit
Fit is the average pairing score against carrot, potato, butter, ham, flour, milk, sugar. 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.
