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 ↓
Eggs, Stuffed
Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the filling
Cut the hard-boiled eggs in half lengthwise and remove the yolks.
Pound the yolks with butter, chopped ham, parsley, salt, and pepper.
Refill the egg whites with the yolk mixture.
Bake and serve
Sprinkle with bread crumbs and small pieces of butter.
Brown in a 400°F (200°C) oven.
Serve very hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Form the rich, creamy filling that holds the stuffed eggs together.
- Butter
- Adds richness and moisture to the yolk filling and helps the topping brown.
- Bread crumbs
- Form a crisp, golden topping that browns in the oven.
- Ham
- Adds savory flavor and a little texture to the yolk filling.
The step that matters
Brown in a 400°F (200°C) oven. Browning depends on surface heat reaching the bread crumbs and butter. Too little heat leaves the topping pale and soft, while too long can scorch the crumbs before the filling warms through.
Swap the parsley
How well each one fits the dish's main ingredients (egg, butter, ham, pepper, bread):
- Parsleythe original
- Nutmegfits about as well
- Thymefits less well
- Marjoramfits less well
Fit is the average pairing score against egg, butter, ham, pepper, bread. Candidates are from the same food group and used in at least 100 recipes.
