Why it works: Butter and milk 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 ↓
Swiss Rolls
Ingredients
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the dough
Beat the eggs and sugar together, then add the lard or butter and mix well.
In a separate bowl, combine the flour, salt, and yeast, then mix the dry ingredients into the egg mixture to form a stiff dough.
Let the dough rise for six hours.
Shape and bake
Roll out the dough and spread butter over the surface.
Fold the dough and cut it into round or oblong shapes.
Place the rolls in a pan and let them rise for two hours.
Bake in a hot oven at 400°F (200°C) for about 20 minutes.

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
- Eggs
- Add structure and richness to the stiff dough as they set in the oven.
- Flour
- Forms the gluten network that gives the dough its structure and chew.
- Yeast
- Produces gas as it feeds, making the dough rise and become light.
- Lard or butter
- Adds fat that tenderizes the crumb and carries flavor.
- Sugar
- Feeds the yeast and adds sweetness and mild browning.
The step that matters
Letting the dough rise for six hours. Yeast needs enough time to produce gas and develop flavor. Rising too short leaves the rolls dense, while over-rising can weaken the structure so they collapse in the oven.
