Stuffed Eggs

  2. Add salt, onions, black pepper, and parsley to the sauce.

  3. When thick, add butter and strain the sauce.

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

What each ingredient does

Eggs
Hard-boiled whites hold the filling, and the yolks form the creamy base of the stuffing.
Flour
Cooked slowly in milk, it thickens the Bechamel sauce into a smooth, body-rich coating.
Milk
Forms the liquid base of the Bechamel sauce, which thickens as the flour cooks.
Ham or dried beef
Adds savory, salty flavor to the yolk filling.
Butter
Adds richness and a smooth, silky texture to both the filling and the sauce.
Onions
Add aroma and savory sweetness to the Bechamel sauce.

The step that matters

Boil the flour in milk slowly. Cooking the flour slowly in milk, stirring as it heats, lets the starch swell and thicken evenly. Rushing the heat can scorch the milk or leave the sauce lumpy and floury-tasting.

Swap the onion

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

  1. Shallotfits better
  2. Asparagusfits better
  3. Chivefits better
  4. Onionthe original

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