Why it works: Parsley and carrot match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 8,053 recipes. Both carry 2,4-decadienal, which smells seaweed. The science ↓
Ordinary Rule for Meat Soup
Ingredients
Directions
Make the broth
Combine 1 quart of cold water with 1 pound of meat and bone in a pot.
Bring to a boil, adding boiling water from a kettle if the liquid evaporates.
Color and serve
Add pounded parsley, celery, or grated carrot a few moments before serving for color.
For additional color, use burnt sugar or pounded spinach.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Meat and bone
- Provides the main flavor and body of the broth as it simmers in water.
- Parsley
- Adds a fresh herbal aroma and bright green color when added near the end.
- Celery
- Contributes a mild savory aroma and a fresh green tint when added near the end.
- Grated carrot
- Adds a little natural sweetness and orange color to the finished soup.
- Spinach
- Adds green color to the soup when pounded and used for coloring.
The step that matters
Bring to a boil and top up the liquid. Keeping the pot's liquid level steady with boiling water helps the meat and bone stay submerged and cook evenly, while a rolling boil can cloud the broth. Adding cold water instead would cool the pot and slow the extraction of flavor.
Swap the spinach
