Scotch Broth

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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Neck of mutton
Gives the broth its meaty flavour and body as it simmers.
Barley
Thickens the broth and adds a chewy texture as it cooks.
Carrots
Add natural sweetness and colour to the soup.
Cabbage
Adds bulk and a mild, sweet vegetable flavour as it softens.

The step that matters

Skimming the foam. Foam that forms early contains coagulated proteins and impurities. Removing it keeps the broth clear and clean-tasting rather than cloudy or scummy.

Swap the onion

How well each one fits the dish's main ingredients (barley, mutton, carrot, cabbage, parsley, celery, pepper):

  1. Turnipfits better
  2. Leekfits better
  3. Parsnipfits better
  4. Onionthe original

Fit is the average pairing score against barley, mutton, carrot, cabbage, parsley, celery, pepper. Candidates are from the same food group and used in at least 100 recipes.
