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 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 350°F (175°C).
Spread the butter in bits over the bottom of a baking dish.
Assemble
Add a layer of cheese, then break the eggs on top.
Season with salt and pepper, and pour a little cream over the eggs.
Add another layer of cheese.
Bake and serve
Bake for 10 minutes, or until the eggs are set.
Garnish with parsley and serve hot.

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, tender custard-like texture as they cook.
- Parmesan cheese
- Adds savoury, salty flavour and browns on the surface as it bakes.
- Butter
- Adds richness and helps keep the dish from sticking to the baking dish.
- Cream
- Adds moisture and softness to the eggs, keeping them tender.
The step that matters
Baking until the eggs are just set. Egg proteins set with heat and turn rubbery if overcooked. Pulling the dish once the whites are firm but yolks still look soft keeps the texture tender.
Swap the parsley
How well each one fits the dish's main ingredients (egg, parmesan cheese, butter, cream, pepper):
- Nutmegfits about as well
- Parsleythe original
- Tarragonfits about as well
- Celeryfits less well
Fit is the average pairing score against egg, parmesan cheese, butter, cream, pepper. Candidates are from the same food group and used in at least 100 recipes.
