Why it works: Carrot and celery match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and 10,172 recipes mention both. Both carry myristicin, which smells spice, warm. The science ↓
The recipe
Ingredients
Contains: milk (auto-detected from the ingredients and method; we can miss things, so check labels)
Directions
Prepare the vegetables
Soak the shredded vegetables in cold water, then drain them.
Fry and simmer
Fry the vegetables in butter until golden brown, then drain the butter from the vegetables.
Add enough stock to cover the vegetables and bring the mixture to a near boil.
Combine this with the required amount of stock or broth and simmer gently for 2 hours.
Allow 1 cup of broth per person.
Finish and serve
If using, boil asparagus tips, peas, or lettuce in weak stock or water until tender.
Add the cooked vegetables to the soup before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Carrot
- Adds sweetness, colour and body to the soup as it simmers.
- Leek
- Contributes a mild onion-like aroma and soft texture after long cooking.
- Turnip
- Adds a mild, slightly peppery flavour and firm texture to the broth.
- Onion
- Builds savoury depth and aroma when fried in butter before simmering.
- Celery
- Adds a fresh, herbal aroma that rounds out the vegetable flavour.
The step that matters
Frying the vegetables until golden brown. Browning the vegetables in butter develops sweet, toasted flavours through the Maillard reaction and caramelisation. Pale, under-fried vegetables give a flatter, blander broth, while over-browning can taste bitter.
Flavor stand-ins for the asparagus
The recipe marks asparagus as optional. How well each one fits the dish's main ingredients (carrot, leek, turnip, onion, celery, butter):

- Asparagusthe original
Fit is the average pairing score against carrot, leek, turnip, onion, celery, butter. 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).
