Why it works: Bread and milk are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 11,466 recipes. Both carry 2-undecenal, which smells sweet. The science ↓
Lemon Toast
Ingredients
Directions
The book says “a very slow oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the toast
Preheat the oven to 350°F (175°C).
Cut the bread into rounds using a large cookie cutter.
Toast the rounds in a slow oven until dry and light brown.
Make the batter
In a bowl, mix the lemon oil, sugar, egg, and milk.
Add flour until the batter reaches the right consistency.
Bake and serve
Dip each round of toast into the batter, coating both sides.
Place the coated toast on oiled baking tins.
Dust with pulverized sugar and bake for 10 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Zwieback or light white bread
- Forms the base; drying it in the oven lets it soak up batter without falling apart.
- Egg
- Adds structure and richness, helping the batter set around the toast.
- Milk
- Provides moisture and softness to the batter, soaking into the bread.
- Sugar
- Adds sweetness and helps the top brown lightly during baking.
- Lemon oil
- Gives the batter its bright lemon aroma and flavour.
- Flour
- Thickens the batter so it coats the toast rather than running off.
The step that matters
Toasting the rounds until dry. Bread that is only lightly toasted stays soft and can turn soggy or collapse when dipped in the batter. Drying it fully lets the rounds absorb the custard-like batter while keeping their shape.

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