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 ↓
Peas Soup Without Meat
Ingredients
Directions
Prepare
Rinse the peas and remove any worm-eaten ones.
Combine the peas and cold water in a large pot, then bring the mixture to a boil.
Make the soup
Melt the butter in a skillet and fry the onions, carrots, and turnips in it until browned.
Add the fried vegetables to the pot along with black pepper and salt.
Simmer gently, stirring often, until the vegetables are tender enough to pass through a sieve.
Rub the mixture through a sieve into a clean pot.
Bring the soup to a boil.
Add the sliced celery and adjust seasoning if needed.
Cook for an additional 20 minutes.
Serve
Serve hot with diced fried or toasted bread.

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 and give it body.
- Onions
- Browning in butter builds savoury sweetness and depth of flavour.
- Turnips
- Soften during simmering and add body and mild sweetness to the purée.
- Carrots
- Browning adds sweetness and colour, and they thicken the purée as they soften.
- Butter
- Fat that carries flavour and helps the vegetables brown in the skillet.
The step that matters
Simmer until the vegetables pass through a sieve. If the peas and vegetables are undercooked, they will not break down into a smooth purée and the soup will stay grainy. Stirring often prevents the bottom from scorching while the starches soften.
Swap the peas
How well each one fits the dish's main ingredients (onion, carrot, turnip, butter, pepper, celery, vinegar):
- Beansfits better

Fit is the average pairing score against onion, carrot, turnip, butter, pepper, celery, vinegar. Candidates are from the same food group and used in at least 100 recipes.
