Why it works: Lemon and pepper match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Baked Eggs, Gratin Sttle
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 the eggs
Boil the eggs until hard, then remove the shells and slice them.
Arrange the slices closely in a dish.
Make the sauce
In a saucepan, combine the white sauce, butter, Parmesan cheese, lemon juice, and egg yolks.
Season the sauce with salt, pepper, and nutmeg.
Stir the sauce over low heat until it thickens.
Remove the sauce from heat.
Add the shredded eggs to the sauce.
Bake and serve
Fill the dish with the sauce mixture.
Smooth the top of the dish.
Sprinkle fried bread crumbs and additional Parmesan cheese over the top.
Place the dish in a very hot oven at 400°F (200°C) for a few minutes to gratinate.
Serve.

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, sliced base and body of the gratin.
- Egg yolks
- Enrich the sauce and help it thicken and set smoothly when heated.
- Parmesan cheese
- Adds savory, salty flavor and browns on the surface when baked.
- Butter
- Adds richness and a smooth, silky mouthfeel to the sauce.
- White sauce
- Forms the creamy base that binds the eggs together.
The step that matters
Stir the sauce over low heat until it thickens. Egg yolks can scramble if the sauce gets too hot. Gentle, low heat lets the yolks thicken the sauce smoothly without curdling.
