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 ↓
Pea Soup
Ingredients
Directions
Prepare
Soak the split peas in cold water for several hours.
Melt the butter in a large pot over medium heat.
Drain the peas and add them to the pot along with the onion and sliced vegetables. Stir for 5 minutes, ensuring they do not brown.
Make the soup
Add the water, stir in the MARMITE, and season with pepper and salt.
Bring to a gentle boil and skim off any foam.
Let the soup simmer slowly until the peas are tender.
Pass the soup through a sieve and reheat it.
Add the fried bread and a little dried mint before serving.

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 and thicken it as they break down during simmering.
- Butter
- Adds richness and carries flavour when the vegetables are softened in it.
- Onion
- Builds savoury sweetness and aroma as it softens with the other vegetables.
- Marmite
- Adds deep savoury, umami flavour to the soup base.
The step that matters
Stir the vegetables without browning them. Gently softening the onion and vegetables in butter builds sweetness and a clean flavour. Browning turns them bitter and dark, which changes the colour and taste of a pale pea soup.

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