Why it works: Butter and bread are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 27,232 recipes. Both carry delta-decalactone, which smells sweet, creamy. The science ↓
Baked Potatoes and Eggs
Ingredients
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 potatoes
Bake the potatoes at 350°F (175°C) until tender.
Remove the potatoes, mash them, and mix in milk, butter, salt, paprika, and nutmeg.
Fill and bake
Half fill the potato shells with the mixture and place them in a baking pan.
Break an egg into each potato shell.
Top with grated cheese and buttered bread crumbs.
Bake until golden brown and the eggs are set.

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 holds the filling and becomes fluffy when baked and mashed.
- Eggs
- Set during baking to firm the filling around the yolk and add richness.
- Milk
- Adds moisture and softness to the mashed potato filling.
- Butter
- Adds fat for richness and a smoother texture in the mashed potato.
- Grated cheese
- Melts and browns on top, adding savory flavor and a golden crust.
The step that matters
Baking until the eggs are just set. Egg whites set at a moderate heat while yolks stay soft if they are not overcooked. Baking too long makes the yolks dry and rubbery, so watch for set whites and check the color of the top.
Swap the nutmeg
How well each one fits the dish's main ingredients (potato, milk, butter, egg, cheese, bread):
- Nutmegthe original
- Parsleyfits about as well
- Thymefits less well
- Cinnamonfits less well
Fit is the average pairing score against potato, milk, butter, egg, cheese, bread. Candidates are from the same food group and used in at least 100 recipes.
