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

What each ingredient does

Liver
Forms the main body of the dish, cooked quickly to stay tender inside.
Flour
Dry coating that helps the liver slices brown and form a crisp surface when fried.
Bacon
Adds salty, smoky fat that flavours the liver and crisps alongside it.
Dripping
Cooking fat that conducts heat for frying and adds rich flavour to the liver.

The step that matters

Frying the liver over medium‑high heat. Liver is lean and delicate; overcooking toughens its proteins and makes it dry and grainy. Brief, hot frying browns the flour coating while keeping the centre moist.

Swap the onion

The recipe marks onion as optional. How well each one fits the dish's main ingredients (liver, flour, parsley, lemon, butter):

  1. Shallotfits better
  2. Chivefits better
  3. Leekfits better
  4. Onionthe original

Fit is the average pairing score against liver, flour, parsley, lemon, butter. Candidates are from the same food group and used in at least 100 recipes.
