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 and browns, flavouring the pan for the rest of the dish.
- Onion
- Browns in the rendered fat, adding sweetness and savoury depth.
- Flour
- Coats the mixture and thickens the cooking liquid as it stews.
The step that matters
Browning the salt pork and onion. Browning builds deep flavour through the Maillard reaction, and it also thickens the sauce. Pale, under-browned pieces leave the stew tasting flat.
Swap the onion
