Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Potato Omelet
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
Peel the potatoes and cook them until soft.
Mash the cooked potatoes with the butter.
Crumble the breadcrumbs and beat the eggs.
Mix and bake
Mix the mashed potatoes, breadcrumbs, and eggs together with a little milk.
Pour the mixture into a deep dish and score the top.
Bake at 400°F (200°C) until nicely browned.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Provide the bulk and soft, starchy body of the omelet.
- Eggs
- Bind the mixture and help it set firm when baked.
- Breadcrumbs
- Absorb moisture and add structure to hold the potato mash together.
- Butter
- Adds richness and fat, contributing flavor and a tender texture.
The step that matters
Baking until nicely browned. Baking long enough lets the eggs set and the surface brown through dry heat. Pulling it too early can leave the center wet and loose.
Swap the potato
How well each one fits the dish's main ingredients (egg, butter, milk):
- Potatothe original
- Asparagusfits about as well
- Chivefits less well
- Leekfits less well
Fit is the average pairing score against egg, butter, 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.
