Why it works: Carrot and celery match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 10,173 recipes. Both carry myristicin, which smells spice, warm. The science ↓
Julienne Soup
Ingredients
Directions
Prepare the vegetables
Cut the vegetables into long, narrow strips.
Soak the strips in cold water, then drain.
Cook the soup
Brown the vegetables lightly in butter.
Remove from butter and cover with a little stock, bringing it slowly to a boil.
Add the remaining stock, salt, and pepper, and simmer for 2 hours.
Serve without straining. Optionally, add boiled asparagus tips, lettuce, shredded green peas, and string beans cut into half-inch lengths.

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 broth as it simmers.
- Turnip
- Adds a mild, slightly sweet flavour and firm texture after long simmering.
- Onion
- Builds savoury depth and aroma when lightly browned in butter.
- Celery
- Contributes aromatic flavour that underpins the broth.
- Stock
- Forms the liquid base that carries the flavour of the soup.
The step that matters
Browning the vegetables lightly in butter. Browning develops savoury, caramelised flavours through the Maillard reaction. Browning too hard can scorch the butter and make the soup taste bitter, so keep the colour light.
