Flour and milk barely smell alike, yet cooks put them together in 78,219 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
Provide the main protein, which becomes tender and moist as it gently steams in the bag.
Flour
Lightly thickens the cooking liquid, giving the stew a slightly body-rich texture.
Onion
Adds aromatic sweetness and flavor that infuses the eels as they cook.
Milk, water, or stock
Provides moisture so the eels steam rather than dry out in the bag.

The step that matters

Sealing the paper bag. A tightly sealed bag traps steam so the eels cook gently in their own moisture; a loose seal lets steam escape and the fish can dry out.

Swap the onion

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

  1. Carrotfits better
  2. Parsnipfits better
  3. Shallotfits better
  4. Onionthe original

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