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 ↓
Winter Vegetable Soup
Ingredients
Directions
Make the soup
In a large pot, melt the butter over medium heat.
Add the chopped turnips, carrots, potatoes, onions, celery, and sweet herbs; fry until browned.
Pour in the water and season with salt and pepper.
Bring to a boil and reduce the heat; simmer until the soup is reduced to 3 quarts.
Serve
Serve hot with fried toasted bread.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Fat that browns the vegetables and carries their aroma into the soup.
- Turnips
- Firm root vegetable that adds body and a mildly sweet, earthy flavour.
- Potatoes
- Starch that thickens the broth and softens into the soup as it simmers.
- Onions
- Aromatic base that adds savoury depth as they brown in the butter.
The step that matters
Frying the vegetables until browned. Browning builds deep flavour through the Maillard reaction and caramelisation of the sugars. Pale, steamed vegetables give a flatter soup, so they need enough time and heat in the butter before the water goes in.
Swap the onion
How well each one fits the dish's main ingredients (turnip, carrot, potato, celery, butter, pepper, bread):
- Leekfits better
- Parsnipfits better
- Spinachfits about as well
- Onionthe original
Fit is the average pairing score against turnip, carrot, potato, celery, butter, pepper, bread. Candidates are from the same food group and used in at least 100 recipes.
