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 ↓
Stuffed Potatoes
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 potatoes
Cut a slice from the side of each potato and scoop out the inside.
Make the filling
Mash the potato insides and add salt, pepper, butter, and hot milk.
Beat the mixture until very light, then fold in the beaten egg white.
Bake and serve
Refill the potato shells with the mixture and brown in a 400°F (200°C) oven.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Provide the starchy base that mashes into a light, fluffy filling inside the shells.
- Butter
- Adds fat for richness and a smoother, more tender texture to the mashed filling.
- Hot milk
- Adds moisture so the mashed potato becomes soft and spreadable.
- Egg white
- Beaten and folded in to lighten the filling and help it puff and set while baking.
The step that matters
Beat the mixture until very light, then fold in the beaten egg white. Beating incorporates air into the mashed potato, and folding in the beaten egg white keeps that air in the mixture. Overmixing after the egg white goes in deflates it and makes the filling dense.
Swap the parsley
The recipe marks parsley as optional. How well each one fits the dish's main ingredients (potato, pepper, butter, milk, egg, meat, cheese):
- Thymefits about as well
- Parsleythe original
- Nutmegfits about as well
- Dillfits less well
Fit is the average pairing score against potato, pepper, butter, milk, egg, meat, cheese. Candidates are from the same food group and used in at least 100 recipes.
