Why it works: Celery and carrot 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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Dried peas
- Break down during long boiling to give the soup its body and thickness.
- Onions
- Add savory sweetness and aroma as they soften and release flavor into the broth.
- Celery
- Contributes aromatic flavor to the base as it simmers.
- Turnips
- Add mild sweetness and earthy flavor as they cook down into the soup.
- Cold butter
- Stirred in at the end to add richness and a smooth, glossy mouthfeel.
The step that matters
Adding water during the second boil. The soup thickens as the peas keep cooking and starch leaches out. Adding water when it gets too thick keeps the texture pourable and prevents scorching on the bottom of the pot.
Swap the peas
How well each one fits the dish's main ingredients (onion, celery, carrot, turnip, pepper, butter, bread):
