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
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the toast
Beat the yolks of the eggs, then add the milk.
Soak the bread in the egg and milk mixture.
Fry the soaked bread in butter until delicately browned.
Make the meringue and syrup
Beat the egg whites until stiff, then add 2 tablespoons of powdered sugar and a pinch of baking powder.
Heap the meringue irregularly on the toast.
Make a syrup by mixing boiling water, lemon juice, and granulated sugar, then pour it carefully around the toast.
Brown and serve
Place the toast under the broiler or in the oven at 400°F (200°C) to brown slightly.
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 whipped into meringue give the topping its airy structure.
- Bread
- Soaks up the egg and milk mixture and fries to a crisp, golden base.
- Milk
- Thins the egg mixture so it soaks into the bread and keeps the toast moist.
- Granulated sugar
- Sweetens the lemon syrup and adds sweetness to the finished dish.
- Powdered sugar
- Dissolves easily into the whipped whites, helping the meringue stay stable and glossy.
- Lemon
- Adds acidity and aroma to the syrup that poured around the toast.
The step that matters
Beat the egg whites until stiff. Whites must be whipped to firm peaks so the meringue holds its shape and browns lightly under heat. Underbeaten whites collapse and soak into the toast.
