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 Pea Soup
Ingredients
Directions
Prepare
Wash the split peas, discarding any that float.
Make the soup
In a saucepan, combine the peas, broth or water, butter, meat scraps, turnip, carrot, onion, thyme, and celery.
Boil slowly, stirring frequently to prevent burning, until the peas dissolve.
Rub the soup through a sieve and season with salt and pepper.
Boil again for a few minutes.
Serve
Serve in a tureen with toasted bread cubes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Split peas
- Break down during long simmering to thicken the soup into a smooth body.
- Meat broth or water
- Provides the liquid that carries the peas and vegetables as they soften.
- Meat scraps and bones
- Release savory flavour and body into the broth during slow simmering.
- Butter or drippings
- Adds fat that carries flavour and gives the soup a richer mouthfeel.
- Onion
- Contributes aromatic sweetness and savoury depth as it cooks down.
The step that matters
Boil slowly and stir frequently. Peas are starchy and settle on the bottom of the pan, where they scorch easily at high heat. Gentle simmering with regular stirring keeps the soup from burning and lets the peas break down evenly.
