Why it works: Pepper and tomato are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 17,923 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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

What each ingredient does

Eels
Firm, fatty flesh that browns in the pan and stays moist under a flour coating.
All-purpose flour
Dredging coat that browns in the fat and helps form a crisp surface on the eels.
Butter
Adds richness and browning flavour to the frying fat.
Lard
High-heat frying fat that gives a crisp, golden surface without burning as quickly as butter.
Tomato ketchup
Adds sweetness and acidity to the pan gravy.

The step that matters

Fry until light brown before turning. The flour coating sets and browns only when the fat is hot and the eels are left undisturbed. Turning too early tears the coating and steams the surface instead of crisping it.

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.
