  5. Return the soup to the kettle.

Thicken and finish

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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

What each ingredient does

Veal knuckle
Gives the soup a rich, savory base as it simmers into broth.
White button onions
Soften during simmering and add sweetness and body to the soup.
Bread
Breaks down during simmering and pressing, adding body and helping thicken the soup.
Butter and flour
Form a roux-style paste that thickens the boiling soup when stirred in.
Cream
Adds richness, fat, and a smooth, mellow texture to the finished soup.

The step that matters

Stirring in the butter and flour mixture. Flour must be fully blended into the fat and then stirred into boiling liquid so it thickens evenly. Adding it unblended or without constant stirring can cause lumps and uneven thickening.

Swap the onion

How well each one fits the dish's main ingredients (veal, cream, bread, butter, flour, pepper):

  1. Leekfits better
  2. Shallotfits about as well
  3. Spinachfits about as well
  4. Onionthe original

Fit is the average pairing score against veal, cream, bread, butter, flour, pepper. Candidates are from the same food group and used in at least 100 recipes.
