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 dough
In a bowl, combine the scalded and cooled milk, salt, sugar, and butter.
Soften the yeast cake in tepid water and add it to the mixture.
Stir in the rye flour and white flour until well combined.
Mould the dough and set it to rise in a warm place until it doubles in size.
Shape and bake
Shape the risen dough into loaves and place them in a baking pan.
Bake the loaves at 350°F (175°C) until golden brown.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

Butter and flour 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
- Rye flour
- Gives the bread its distinctive flavour and a denser, moister crumb than wheat flour alone.
- White flour
- Provides gluten for structure so the dough can trap gas and hold its shape.
- Yeast
- Produces carbon dioxide during fermentation, which makes the dough rise.
- Milk
- Adds moisture and softness, and its sugars help the crust brown.
- Butter
- Adds fat that tenderises the crumb and gives a richer texture.
- Sugar
- Feeds the yeast and promotes browning in the crust.
The step that matters
Rising until the dough doubles. Yeast needs a warm, sufficient rise to build gas and air structure. Under-proofing leaves a dense loaf, while over-proofing lets the gluten collapse, so the dough should be judged by its size rather than the clock.
