Shared aroma: (e,e)-2,4-decadienal (fatty, deep fried).
Lemon and egg barely smell alike, yet cooks put them together in 44,316 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lemon
- Provides the sharp acidity and fragrant aroma that flavor the filling.
- Eggs
- Thicken the filling as it cooks, and the whites whip into the stiff topping.
- Pie crust
- Holds the filling in a pre-baked shell.
The step that matters
Cook the filling until thickened. Egg proteins set as the mixture heats, but they can curdle or scramble if it gets too hot too fast. Gentle double-boiler heat and frequent stirring keep the filling smooth and evenly thickened.
