Why it works: Parsley and thyme match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 9,057 recipes. Both carry cuminaldehyde, which smells Spicy, cumin. The science ↓
Leg Op Beep, or Shin of Beef Soup
Ingredients
Directions
Place the beef in a large saucepan with the cold water.
Heat over a low flame and skim off any scum as it comes to a boil.
Once the scum is removed, add the turnips, carrots, onions, celery, parsley, thyme, savory, allspice, and black peppercorns.
Cover the saucepan tightly and let it simmer slowly for 4 hours or until the meat is tender.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef leg or shin
- Breaks down into tender meat and releases gelatin and flavor into the broth during long simmering.
- Cold water
- Forms the broth; starting cold lets scum rise gradually so it can be skimmed off as the liquid heats.
- Onions
- Add savory sweetness and aroma to the broth as they soften during simmering.
- Carrots
- Add natural sweetness and body to the broth as they cook down.
- Celery
- Adds a fresh, aromatic vegetable flavor that deepens during the long simmer.
The step that matters
Skimming the scum as the water heats. Scum is coagulated proteins and impurities that rise to the surface as the broth approaches a boil. Removing it before it re-mixes keeps the soup clear and clean-tasting.
