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 ↓

Ingredients
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Butter a small baking dish and sprinkle it with a little grated cheese.
Assemble and bake
Carefully drop the eggs into the dish, ensuring not to break the yolks.
Sprinkle the eggs with salt, pepper, the remaining cheese, and chopped parsley.
Bake in a hot oven at 400°F (200°C) until set.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set into a firm custard-like texture as they cook, forming the body of the dish.
- Grated cheese
- Melts and browns on top, adding savory flavor and a golden crust.
- Butter
- Greases the dish so the eggs release cleanly and adds richness to the flavor.
The step that matters
Dropping the eggs without breaking the yolks. Yolks that break before baking spread into the whites and leave the dish looking uneven. Keeping each yolk whole helps the eggs set neatly in separate, rounded portions.
