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

What each ingredient does

Tripe
Forms the main body of the dish, becoming crisp and golden in the batter.
Batter
Coats the tripe, forming a crisp golden crust when fried.
Onions
Add sweetness and browning as they fry in the lard.
Lard
Conducts heat to fry the coating quickly, giving a golden, crisp surface.

The step that matters

Frying the tripe in boiling lard until golden brown. The lard must be hot enough to set the batter quickly; if it is too cool, the coating absorbs more fat and turns greasy instead of crisp.

Swap the onion

How well each one fits the dish's main ingredients (butter, mustard, vinegar):

  1. Horseradishfits better
  2. Shallotfits better
  3. Radishfits better
  4. Onionthe original

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