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

What each ingredient does

Hard-boiled eggs
Provide the firm white shells that hold the filling and the yolks for the paste.
Butter
Adds richness and helps the yolks blend into a smooth, spreadable paste.
Cream
Loosens the yolk mixture, adding moisture so it forms a soft, smooth paste.

The step that matters

Steam the filled egg whites until hot. Steam heats the filling gently. Overheating can make the yolk paste dry, grainy, or rubbery, so heat only until the filling is hot throughout.

Flavor stand-ins for the onion

  2. Spinachbetter flavor fit
  3. Chivebetter flavor fit
  4. Onionthe original

Fit is the average pairing score against egg, cream, butter, parsley, pepper. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
