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 ↓
Egg Pie
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
Cut up the hard-cooked eggs and mix them with the rich white sauce.
Cover the mixture with mashed potatoes.
Bake and serve
Bake in a 350 °F (175 °C) oven until heated through.
Brush the top with melted butter and season with parsley before serving hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Hard-cooked eggs
- Form the main filling and provide a rich, firm body to the pie.
- Rich white sauce
- Binds the chopped eggs together and keeps the filling moist and creamy.
- Mashed potatoes
- Forms the topping that holds in moisture and browns during baking.
- Melted butter
- Adds fat and richness and helps the top brown as it bakes.
