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 ↓
Shin of Beef Soup
Ingredients
Directions
Prepare the bones and meat
Break the shin of beef into small pieces, separating bone from meat and removing marrow.
Place the bones in a pot, cover with cold water, and boil for 4 to 5 hours.
In another pot, brown the marrow and meat over heat, stirring to prevent burning.
Once browned, add 1 quart of water and the lump of salt; boil for 15 minutes.
Make the soup
Add 5 quarts of water, onions, turnips, carrots, celery, sweet herbs, and pepper/spice.
Simmer slowly for 4 to 5 hours.
Remove the fat from the soup and take out 1 cup of the soup to cool.
Stir in 2 tablespoons of flour into the cooled soup, then gradually add it back to the pot.
Stir well and bring to a boil before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Shin of beef
- Provides meat and marrow that build the rich body and flavor of the broth.
- Onions
- Add sweetness and aromatic depth as they soften during the long simmer.
- Flour
- Thickens the soup when stirred in cooled liquid before it returns to the pot.
The step that matters
Stirring the flour into cooled soup. Adding flour directly to hot liquid causes lumps because starch clumps before it can disperse. Mixing it into cooled soup first and adding it back gradually lets the starch hydrate evenly and thicken smoothly.
Swap the onion
