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

What each ingredient does

Raw egg
Binds the parsley, onion, and shallot mixture and coats the bread so it sets when fried.
Bread
Forms the base that soaks up the egg mixture and fries to a crisp golden surface.
Streaked bacon
Adds fat and savory flavor that renders into the frying and browns the pieces.

The step that matters

Fry the dipped bread and bacon over low heat until golden. Low heat lets the egg coating set and the bacon fat render gradually, so the egg does not scorch before the bread and bacon are cooked through.

Swap the onion

How well each one fits the dish's main ingredients (bread, egg, parsley, shallot, pepper, sauce, vinegar):

  1. Chivefits better
  2. Mustardfits better
  3. Capsicumfits better
  4. Onionthe original

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