Why it works: Parsley and pepper match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Ragout of Eggs with Ham or Bacon
Ingredients
Directions
Prepare the filling
Hard-boil the eggs, then cool, shell, and cut them in half.
In a bowl, beat the yolks with an equal amount of white meat, bread crumbs, parsley, eschalot, and anchovy.
Season with cayenne, salt, nutmeg, butter, and mushroom ketchup; mix well.
Cook and serve
Fill the egg white halves with the mixture.
Dip each filled half in the beaten egg yolk.
Fry in butter or brown in a Dutch oven.
Serve on slices of ham or bacon.

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 bulk of the dish, with yolks binding the filling and whites forming the shell.
- White meat from dressed fowl or veal
- Adds protein body and a tender, meaty texture to the filling.
- Bread crumbs
- Absorb moisture and bind the filling so it holds its shape when fried.
- Beaten egg yolk
- Coats the filled halves, helping them brown and form a crisp, set surface when cooked.
- Anchovy
- Adds a savoury, salty depth to the filling.
The step that matters
Dip each filled half in the beaten egg yolk. Egg yolk coats the filling so it stays sealed while frying. If the coating is thin or uneven, the filling can leak into the pan and the surface will brown unevenly.
Swap the nutmeg
How well each one fits the dish's main ingredients (egg, meat, bread, parsley, anchovy, pepper, butter):

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