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 ↓
Another Old Peas Soup
Ingredients
Directions
Make the soup
Boil 5 quarts of water in a large pot.
Add 1 pint of split peas, 1 ounce of butter, 4 pounds of beef, 2 chopped carrots, 3 chopped turnips, 4 heads of celery, 3 chopped onions, salt, and black pepper.
Boil until the peas dissolve and can be easily pulped.
Pass the mixture through a sieve.
Return the soup to the pot over low heat and add 3 ounces of butter and 1 tablespoon of flour.
Add a small piece of lean ham and boil until ready to serve.
Remove the ham before serving.
Serve
Prepare some celery stewed in butter and fried bread cut into dice.
Serve with dried mint sprinkled on top.

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 boiling to thicken the soup and give it body.
- Beef
- Adds savory meaty flavor to the broth as it simmers.
- Butter
- Adds richness and a smooth, rounded mouthfeel to the finished soup.
- Flour
- Helps thicken the soup slightly and adds body to the broth.
- Onions
- Build the aromatic flavor base of the soup as they cook down.
The step that matters
Boil until the peas dissolve and can be easily pulped. Split peas must cook long enough to soften fully, otherwise the soup stays grainy and will not pass smoothly through the sieve.
