Why it works: Parsnip and carrot match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 1,097 recipes. Both carry 2-isobutyl-3-methoxypyrazine, which smells green bell pepper, earthy. The science ↓
Beef Soup
Ingredients
Directions
Place the beef in a kettle with the cold water and bring to a boil over low heat for 1 hour.
Add the onions, parsnips, carrots, and potatoes, and boil for another hour.
Stir in the parsley and flour, and cook for an additional 5 minutes.
Season with salt and pepper, then serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lean beef
- Provides the main protein and meaty flavor that the broth is built on.
- Potatoes
- Break down slightly as they cook, giving the broth body and a thicker texture.
- Flour
- Thickens the broth slightly as it cooks in the liquid.
