Why it works: Pepper and parsley match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and 34,118 recipes mention both. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
The recipe
Ingredients
Contains: egg, milk (auto-detected from the ingredients and method; we can miss things, so check labels)
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the potato mixture
Work the boiled potatoes through a sieve until smooth.
Mix in the egg yolks and cream.
Season and shape
Season with salt, pepper, nutmeg, and chopped parsley.
Roll the mixture into balls.
Cook
Fry gently in butter or brown in a 350°F (175°C) oven on a greased baking sheet.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Add richness and help the mixture hold its shape and set when cooked.
- Cream
- Adds moisture and softness, keeping the mash smooth and tender.
- Butter
- Adds fat and flavour, and browns the outside of the potatoes during cooking.
The step that matters
Fry gently in butter or brown in the oven. Butter's milk solids burn at high heat, so gentle frying gives an even golden colour without a bitter, scorched taste.
Flavor stand-ins for the parsley
How well each one fits the dish's main ingredients (egg, cream, pepper, nutmeg, butter):
- Cinnamonabout as good a flavor fit
- Parsleythe original
- Maceabout as good a flavor fit
Fit is the average pairing score against egg, cream, pepper, nutmeg, butter. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
