Cream and onion barely smell alike, yet cooks put them together in 10,827 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eels (in the method)
- Provide the main body and flavour of the soup as the central ingredient.
- Flour
- Thickens the liquid when mixed into a batter and heated.
- Cream
- Adds richness and body, and helps the flour batter blend smoothly.
- Onion
- Adds savoury, aromatic flavour to the broth.
The step that matters
Simmer until the eels are tender, but do not break the fish. Gentle simmering cooks the fish through while keeping its flesh intact; a hard boil toughens proteins and causes delicate slices to fall apart.
