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

What each ingredient does

Eggs
Bind the milk and bread together and set into a tender, custard-like interior when cooked.
Milk
Moistens the bread and carries the egg into a soft, custardy texture.
Stale bread
Absorbs the egg mixture and holds its shape, so the slices brown well without falling apart.
Butter
Coats the griddle and browns the surface of the bread, adding richness and flavor.

The step that matters

Dip the bread briefly and evenly. Stale bread absorbs liquid quickly. Over-soaking makes the slices soggy and fragile, so they tear on the griddle and brown unevenly. A quick, even dip gives a moist interior with a sturdy crust.

Swap the cinnamon

How well each one fits the dish's main ingredients (egg, milk, bread, butter):

  1. Nutmegfits about as well
  2. Cinnamonthe original
  3. Parsleyfits less well
  4. Capersfits less well

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