Why it works: Carrot and parsley 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 ↓
Beef Soup
Ingredients
Directions
Make the broth
Place the beef in a large kettle with cold water and salt.
Cook soon after breakfast.
Skim off any scum that rises when it boils.
Let it boil slowly until one hour before dinner.

Add the browned mixture to the soup.
Season with pepper and salt.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef
- Provides the meat and rich flavor that the broth is built on.
- Potatoes
- Add starch that softens during simmering and thickens the soup slightly.
- Flour
- Browned in butter, it thickens the soup and adds a toasty, nutty flavor.
- Onions
- Contribute sweetness and aroma as they soften in the broth.
- Cabbage
- Adds body and a mild sweetness as it cooks down in the soup.
The step that matters
Skimming the scum as it boils. Scum is coagulated protein and impurities that rise from the meat; removing it keeps the broth clear and clean-tasting. Skimming early matters because it is easiest before the liquid is simmering vigorously and the scum has been stirred back in.
Swap the cabbage
