Why it works: Bread and butter 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).
Mix bread crumbs, sugar, water, egg yolks, butter, lemon juice, and lemon rind in a bowl.
Pour the mixture into a pie dish lined with pastry.
Make the meringue and finish
In a separate bowl, beat the egg whites with 4 tablespoons of sugar and your chosen flavoring until stiff.
Spread the meringue on top of the pie after it has baked.
Return the pie to the oven for a few minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Bind the filling and enrich it, helping it set into a creamy custard.
- Bread crumbs
- Thicken the filling and give it body.
- Lemon juice
- Adds acidity and bright lemon flavor that balances the sugar.
- Egg whites
- Whipped with sugar to form a stable meringue that browns when baked.
The step that matters
Beating the egg whites until stiff. Egg whites must be whipped until they hold firm peaks; under-whipped whites collapse and weep, while sugar added gradually helps them stay stable and glossy.
Swap the lemon
How well each one fits the dish's main ingredients (bread, sugar, egg, butter):
