Why it works: Pepper and parsley 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 the filling
Cut a slice from the top of each baked potato and scoop out the insides.
Mash the potato insides and season with salt, pepper, parsley, and butter.
Heat the mixture in hot milk and fold in the beaten egg whites.
Stuff and bake
Refill the potato skins with the mixture, sprinkle with grated cheese.
Bake in a hot oven at 400°F (200°C) for about 6 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Beaten whites trap air, giving the filling a light, fluffy texture.
- Butter
- Adds fat and richness, making the mashed potato smooth and flavorful.
- Hot milk
- Moistens the mashed potato and keeps the filling soft and creamy.
- Grated cheese
- Melts and browns on top, adding flavor and a golden crust.
The step that matters
Folding in the egg whites. Beaten egg whites hold air only if they are folded in gently. Stirring vigorously deflates them, leaving a dense filling instead of a light, fluffy one.
Swap the parsley
The recipe marks parsley as optional. How well each one fits the dish's main ingredients (potato, pepper, butter, milk, egg, cheese):
- Parsleythe original
- Nutmegfits about as well
- Thymefits about as well
- Dillfits about as well
Fit is the average pairing score against potato, pepper, butter, milk, egg, cheese. Candidates are from the same food group and used in at least 100 recipes.
