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 Toast
Ingredients
Directions
Make the toast
Beat the yolks of the eggs.
Add the milk to the beaten yolks.
Soak the bread in the egg and milk mixture.
Fry the soaked bread in butter until golden brown.
Top with meringue
Beat the egg whites until stiff.
Add 2 tablespoons of powdered sugar and a pinch of baking powder to the stiff egg whites.
Heap the meringue irregularly on the fried toast.
Place the toast under the broiler or in the oven to brown slightly.
Serve with syrup
Mix boiling water, lemon juice, and granulated sugar to make a syrup.
Pour the syrup carefully around the toast.
Garnish with spoonfuls of bright jelly.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Yolks enrich the soaking custard and whites whip into the meringue topping.
- Milk
- Moistens the bread and forms a custard-like soak that sets when fried.
- Bread
- Acts as the base that soaks up the egg mixture and crisps in butter.
- Granulated sugar
- Sweetens the lemon syrup and adds sweetness to the dish.
- Powdered sugar
- Sweetens the meringue and helps it hold a smooth, stable texture.
The step that matters
Browning the meringue. Meringue can weep or brown unevenly if overbaked or left too long; a brief, watched broil browns the peaks slightly while keeping the topping soft inside.

Fit is the average pairing score against egg, milk, sugar, bread, butter, crab. Candidates are from the same food group and used in at least 100 recipes.
