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

What each ingredient does

Eels
Provide the main protein, which firms and browns during frying while staying moist inside.
Flour
Forms a dry coating that browns in the hot fat and gives the eels a crisp exterior.
Butter
Adds richness and flavor to the frying fat and helps the coating brown.
Lard
Provides a high-heat frying fat that browns the coating evenly.
Tomato ketchup
Adds sweetness and acidity that flavor the pan sauce.

The step that matters

Fry until light brown, then turn and baste. The eels are covered and fried in hot fat, so the flour coating must reach a golden color without burning. Turning and basting keeps the flesh moist while the coating browns evenly on both sides.

Swap the tomato

How well each one fits the dish's main ingredients (pepper, flour, butter, ketchup):

  1. Capsicumfits better
  2. Shallotfits better
  3. Turnipfits better
  4. Tomatothe original

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