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

What each ingredient does

Hard-boiled egg yolk
Mashed smooth, it gives the filling a creamy, binding base.
Melted butter
Adds fat and richness, giving the filling a smooth, spreadable texture.
Grated cheese
Provides the main flavor and, with the butter and yolk, the body of the spread.
Water
Loosens the mixture so it reaches a spreadable consistency.

The step that matters

Moisten the mixture with water. Too little water leaves the filling stiff and hard to spread, while too much makes it runny and soggy on the bread. Add it gradually until the spread holds together yet moves easily.

Swap the mustard

How well each one fits the dish's main ingredients (egg, butter, cheese, pepper, bread):

  1. Capsicumfits better
  2. Asparagusfits about as well
  3. Potatofits about as well
  4. Mustardthe original

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