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 ↓
Lemon 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 the filling
Preheat the oven to 350°F (175°C).
In a bowl, mix sugar, butter, egg yolks, lemon juice, lemon rind, hot water, and grated bread until well combined.
Pour the mixture into a pie crust and bake until set.
Top and brown
Beat the egg whites until stiff, then sweeten to taste.
Spread the beaten egg whites over the baked pie and return to the oven to brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Yolks thicken the filling, and whipped whites form the stiff meringue topping.
- Sugar
- Sweetens the filling and the meringue, balancing the lemon's acidity.
- Lemon
- Juice and rind supply the sharp, aromatic flavour that defines the pie.
- Bread
- Grated bread soaks up liquid and gives the filling body and a soft, set texture.
The step that matters
Beating the egg whites until stiff. Egg whites need to be beaten until they hold firm peaks, because any trace of yolk or grease will prevent them from whipping properly. Sweetening after beating keeps the foam stable.
Swap the lemon
How well each one fits the dish's main ingredients (sugar, butter, egg, bread):
- Vanillafits better
- Figfits better
- Datesfits about as well
- Lemonthe original
Fit is the average pairing score against sugar, butter, egg, bread. Candidates are from the same food group and used in at least 100 recipes.
