Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Provide the main body of the dish, forming the filling base.
- Butter
- Adds fat and richness, carrying flavor and keeping the warm filling moist.
- Tomato catsup
- Adds sweetness and acidity that balance the savory sauce.
- Mushroom catsup
- Adds deep savory, umami flavor to the sauce.
- Worcestershire sauce
- Adds tangy, fermented savory depth that rounds out the sauce.
- Dry mustard
- Adds a sharp, pungent bite that cuts the richness of the yolks and fat.
The step that matters
Heat until warmed through. The hard-boiled eggs are already cooked, so they only need to warm. Extended heat toughens the egg whites and dries the yolk filling, so heat gently and stop once warmed.
Swap the mustard
How well each one fits the dish's main ingredients (egg, butter, tomato, mushroom, sauce):
- Capsicumfits better
- Asparagusfits better
- Shallotfits better
- Mustardthe original
Fit is the average pairing score against egg, butter, tomato, mushroom, sauce. Candidates are from the same food group and used in at least 100 recipes.
