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
Make the soup base
Combine peas and cold water in a large pot.
Boil until peas are tender.
Melt butter in a skillet and gently fry onions, carrots, and turnips until browned.
Add fried vegetables to the pot with peas.
Stir in black pepper and coarse sea salt.
Simmer, stirring often, until vegetables are tender enough to pass through a sieve.
Rub mixture through a sieve into a clean pot.
Finish and serve
Bring to a boil.
Add sliced celery and adjust seasoning if needed.
Cook for an additional 20 minutes.
Serve hot with fried or toasted bread on the side.
Optionally add chili vinegar for flavor.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Peas
- Break down when simmered and sieved to give the soup its body and thick texture.
- Onions
- Browning in butter builds sweet, savoury depth in the base.
- Butter
- Fat for frying the vegetables, carrying flavour and aiding browning.
- Carrots
- Add natural sweetness and colour as they soften and brown.
- Turnips
- Soften during simmering and add body and mild earthy flavour to the puree.
The step that matters
Rub the mixture through a sieve. Sieving breaks down the softened peas and vegetable fibres into a smooth, thick purée. If the vegetables are not fully tender, they will not pass through and the soup will be grainy.
Swap the peas
How well each one fits the dish's main ingredients (onion, carrot, turnip, butter, pepper, celery, vinegar):
- Beansfits better
- Lentilsfits better
- Chickpeafits better
- Peasthe original
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.
