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 ↓
Stuffed Potatoes
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Bake the potatoes at 400°F (200°C) until done.
Cut off the tops and scoop out the insides, setting the skins aside.
Make the filling
Mash the potato insides smoothly and mix in the butter, cream, onion, parsley, salt, and cayenne pepper.
Beat in the stiffened egg whites until well combined.
Fill and bake
Fill the potato skins with the mixture, heaping it high.
Stand the filled potato skins in a baking pan and bake until the tops are a delicate brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Provide the bulk of the filling and the hollow skins that hold it.
- Butter
- Adds fat and richness, softening the mashed potato texture.
- Cream
- Adds moisture and richness, keeping the mashed filling smooth.
- Egg whites
- Whipped and folded in, they lighten the filling and help it set and brown.
The step that matters
Beat in the stiffened egg whites until well combined. Egg whites hold air only when whipped stiff, which lightens the filling. Overmixing after folding in deflates that air, leaving a dense filling that rises less in the oven.
Swap the onion
How well each one fits the dish's main ingredients (potato, butter, cream, parsley, pepper, egg):
- Chivefits better
- Spinachfits better
- Leekfits better
- Onionthe original
Fit is the average pairing score against potato, butter, cream, parsley, pepper, egg. Candidates are from the same food group and used in at least 100 recipes.
