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 ↓
Crecy Soup
Ingredients
Directions
Make the vegetable base
Combine sliced carrots, onion, turnip, and celery with boiling water in a pot.
Cook the mixture for 30 minutes.
Strain the vegetables, saving the cooking water.
Finish the soup
Melt butter in a saucepan and add the strained vegetables and sugar.
Heat until very hot, then cover and cook until the vegetables are soft.
Rub the mixture through a fine sieve into a bowl, gradually adding the reserved cooking water. Mix well.
Return the mixture to the saucepan and simmer slowly for 1 hour.
Stir in a small piece of butter before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Carrots
- Add sweetness, body and colour to the soup once puréed.
- Butter
- Adds richness and a silky mouthfeel to the finished soup.
- Onion
- Builds savoury depth as it softens into the base.
- Turnip
- Adds mild earthy flavour and body to the purée.
- Celery
- Contributes aromatic, savoury flavour to the vegetable base.
The step that matters
Rubbing the vegetables through a fine sieve. Pushing the soft vegetables through a fine sieve breaks down their cell walls, producing a smooth purée. Adding the reserved cooking water gradually lets you control the thickness, so the soup does not become too thick or grainy.
