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

What each ingredient does

Butter
Fat that softens the onions and carries flavor into the sauce.
Flour
Thickens the liquid into a sauce when cooked with butter as a roux.
Hard-boiled eggs
Provide the main body of the dish, sliced and warmed in the sauce.
Onions
Add savory sweetness and aroma as they soften in the butter.
Vinegar
Adds acidity that brightens the rich, thick sauce.

The step that matters

Adding the flour roux and liquid gradually. Flour must be cooked briefly in butter and whisked into the liquid slowly so starch granules hydrate evenly. Adding everything at once can form lumps and leave the sauce unevenly thickened.

Swap the onion

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

  1. Capsicumfits better
  2. Shallotfits better
  3. Potatofits better
  4. Onionthe original

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