Why it works: Pepper and nutmeg match in chemistry and in kitchens. They rank in the top 7% of all ingredient pairs, and cooks put them together in 13,015 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Baked Eggs, Gratin Style
Ingredients
Directions
The book says “a very hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Slice the hard-boiled eggs and arrange them in a border on a buttered dish.
Make the sauce
In a saucepan, combine the white sauce, butter, Parmesan cheese, and egg yolks.
Season with salt, pepper, and nutmeg, and stir over medium heat until it thickens.
Add two finely shredded hard-boiled eggs to the mixture and fill the center of the dish.
Bake and serve
Cover the egg border with the remaining sauce and sprinkle with fried breadcrumbs and more Parmesan cheese.
Bake in a very hot oven at 400°F (200°C) for a few minutes until browned, then serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Hard-boiled eggs
- Form the sliced border and shredded filling that give the dish its body.
- Butter
- Adds richness and helps the sauce stay smooth and flavorful.
- White sauce
- Provides a creamy, moist base that binds the dish together.
- Parmesan cheese
- Adds savory flavor and helps the top brown as it bakes.
- Egg yolks
- Thicken the sauce as they set with gentle heat, giving it a custard-like texture.
The step that matters
Stirring the sauce over medium heat. Egg yolks thicken when gently heated but can curdle or scramble if the heat is too high or they are left unstirred. Keep the heat moderate and stir constantly until the sauce thickens smoothly.
Swap the nutmeg
How well each one fits the dish's main ingredients (egg, butter, sauce, parmesan cheese, pepper):
- Parsleyfits better
- Capersfits about as well
- Tarragonfits about as well
- Nutmegthe original
Fit is the average pairing score against egg, butter, sauce, parmesan cheese, pepper. Candidates are from the same food group and used in at least 100 recipes.
