Why it works: Cheese and butter are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 7,962 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓
Eggs in Baked Potatoes
Ingredients
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Bake the potatoes
Bake the potatoes until tender.
Cut off the top and scoop out half of the inside of each potato.
Add the egg and toppings
Crack a raw egg into each potato.
Season with coarse sea salt and cayenne pepper.
Add 1 tablespoon of grated cheese and 1 tablespoon of butter to each potato.
Return the potatoes to a 400°F (200°C) oven for 4 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set and firm up in the potato cavity, forming a soft, cooked centre.
- Butter
- Adds richness and moisture, carrying flavour into the potato.
- Grated cheese
- Melts and browns on top, adding savoury flavour and a golden crust.
- Potatoes
- Provide the starchy base that holds the egg and toppings.
The step that matters
Return the potatoes to the oven for 4 minutes. The egg white sets within minutes while the yolk stays runny if underbaked. Watching the timing matters because the egg keeps cooking from residual heat after it leaves the oven.
Swap the potato
How well each one fits the dish's main ingredients (cheese, egg, butter, pepper):
- Capsicumfits about as well

- Potatothe original
- Mustardfits about as well
Fit is the average pairing score against cheese, egg, butter, pepper. Candidates are from the same food group and used in at least 100 recipes.
