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

What each ingredient does

Calf brains
Form the main body of the balls, giving them a soft, rich filling.
Egg yolks
Bind the mixture together so the balls hold their shape.
Bread crumbs
Absorb moisture and add body, helping the balls keep a firm texture.
Flour
Thickens the mixture slightly and helps it hold together when fried.

The step that matters

Forming and frying the balls. If the mixture is too wet, the balls can fall apart in the hot fat. Frying at a steady heat browns the outside while the inside cooks through, so the surface sets before the balls break.

Swap the sage

How well each one fits the dish's main ingredients (egg, thyme, parsley, bread, flour, pepper):

  1. Marjoramfits better
  2. Winter savoryfits about as well
  3. Sagethe original
  4. Tarragonfits about as well

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