Why it works: Milk and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓

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.
Make the batter
Mix together the flour and sugar in a bowl.
In a saucepan, heat the milk and butter until boiling.
Gradually stir in the flour and sugar mixture.
Beat the eggs, add them with the lemon rind, and stir until thick like dough.
Bake and serve
Lay greased paper on a baking sheet.
Spread the mixture about ¼ inch thick.
Bake in a 350°F (175°C) oven until half done.
Spread jam on the mixture.
Bake again until fully cooked.
Serve cold, whole or sliced into nearly 1‑inch thick pieces.

Flour and butter barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Forms the structure of the dough as it sets in the oven.
- Eggs
- Bind the mixture and add structure and richness as they set.
- Butter
- Adds fat for tenderness and a rich texture.
- Milk
- Adds moisture and helps form a thick, dough-like mixture.
- Sugar
- Sweetens the dough and helps it brown in the oven.
The step that matters
Bake until half done, then again until fully cooked. The sheet must be baked in two stages so the base sets firmly before jam is added and the roll finishes cooking. Underbaking leaves it doughy and hard to slice cleanly, while overbaking dries it out.

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