Why it works: Butter and egg are a kitchen classic. They rank in the top 17% of all ingredient pairs, and cooks put them together in 118,967 recipes. Both carry decanal, which smells soap, orange peel. The science ↓
Transparent Pie
Ingredients
Directions
The book gives no oven temperature. The 300°F (150°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the filling
Cream the butter and mix it with the sugar until well combined.
Add the beaten egg yolks to the butter and sugar mixture and beat well.
Bake and finish
Pour the mixture into a pie crust and bake slowly at 300°F (150°C).
Beat the egg whites and spread them on top of the pie as desired.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds richness and a tender, smooth texture to the filling.
- Sugar
- Sweetens the filling and helps give it a soft, set body when baked.
- Egg yolks
- Thicken and set the filling as they cook, while adding richness.
- Egg whites
- Whipped and spread on top, they add light volume and browning.
The step that matters
Bake slowly at a low temperature. Egg yolks set gently as they heat. Too much heat makes the filling curdle, weep, or turn grainy, so a slow, low bake keeps it smooth and evenly set.
