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

What each ingredient does

Meat and bones
Collagen from the bones and meat dissolves into the liquid, giving the stock body and a rich mouthfeel.
Carrot
Releases natural sugars and aromatic compounds that add mild sweetness and depth to the stock.
Turnip
Adds subtle sweetness and earthy aroma to the broth.
Onion
Contributes savory aroma and sweetness as its compounds release into the simmering liquid.

The step that matters

Bringing the pot to a boil slowly and skimming the scum. Heating gradually lets proteins and impurities rise to the surface as scum, where they can be skimmed off. If they are left to mix back in, they cloud the stock and can add off flavors.

Swap the onion

The recipe marks onion as optional. How well each one fits the dish's main ingredients (meat, carrot, turnip, clove):

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

Fit is the average pairing score against meat, carrot, turnip, clove. Candidates are from the same food group and used in at least 100 recipes.
