Why it works: Pork and onion are a kitchen classic. They rank in the top 10% of all ingredient pairs, and cooks put them together in 18,214 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eels
- Form the main body of the dish, becoming tender as they stew.
- Salt pork
- Renders fat into the pan, adding richness and savory flavor for frying.
- Onion
- Browns in the rendered fat, adding sweetness and aromatic depth to the stew.
- Flour
- Coats the eels so they brown lightly and help thicken the cooking liquid.
The step that matters
Dredge and fry the eels briefly. Flour coating must be fried just until lightly browned; overcooking at this stage can make the coating gummy or bitter, and the eels then stew gently in the water to finish cooking.
Swap the onion
How well each one fits the dish's main ingredients (pepper, pork, flour):
- Capsicumfits better
- Potatofits better
- Turnipfits better
- Onionthe original
Fit is the average pairing score against pepper, pork, flour. Candidates are from the same food group and used in at least 100 recipes.
