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 the peas
Rinse the peas and remove any worm-eaten ones.
In a large pot, combine the peas and cold water, and boil until tender.
Make the soup
In a skillet, melt the butter and fry the onions, carrots, and turnips until browned.
Add the fried vegetables to the pot with the peas, 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 and bring to a boil.
Add the sliced celery and adjust seasoning if needed.
Cook for an additional 20 minutes and serve hot with fried or 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
- Form the body of the soup as they soften and break down into a thick purée.
- Onions
- Add savoury sweetness and depth when fried until browned.
- Carrots
- Contribute natural sweetness and colour, and help thicken the purée when sieved.
- Turnips
- Add mild sweetness and body to the soup once cooked and sieved.
- Butter
- Carries flavour into the frying step and adds richness to the finished soup.
- Celery
- Adds a fresh, aromatic note to the soup near the end of cooking.
The step that matters
Rubbing the mixture through a sieve. The vegetables must be fully tender before sieving, otherwise the purée stays grainy and clogs the sieve. Pressing it through removes fibres and skins, giving the smooth, thick texture the soup depends on.
Swap the peas
How well each one fits the dish's main ingredients (onion, carrot, turnip, butter, pepper, celery, vinegar):

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.
