Why it works: Potato and parsley are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 2,855 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Potato Omelet
Ingredients
Directions
The book says “a brisk oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Mash the boiled potatoes with the butter.
Add the stale bread crumbs, beaten egg, milk, seasoning, and chopped parsley; mix well.
Place the mixture in a buttered dish and smooth the top.
Bake
Cover with a thin layer of fine bread crumbs and dot with small pieces of butter.
Bake in a brisk oven at 400°F (200°C) until golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Form the bulk of the omelet and give it a soft, fluffy body.
- Egg
- Binds the mixture so it holds together and sets when baked.
- Butter
- Adds richness and moisture, and helps the top brown.
- Stale bread crumbs
- Absorb moisture and add body so the mixture holds its shape.
Swap the parsley
How well each one fits the dish's main ingredients (potato, butter, bread, egg, milk):
- Nutmegfits about as well
- Parsleythe original
- Cinnamonfits about as well
- Thymefits less well
Fit is the average pairing score against potato, butter, bread, egg, milk. Candidates are from the same food group and used in at least 100 recipes.
“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.
