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 ↓
Sweet Rusk
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
Scald the sweet milk in a pot.
Add the butter, sugar, and salt to the milk and stir until combined.
When the mixture is lukewarm, add the dissolved yeast cake.
Stir in enough flour to make a batter and let it stand overnight.
In the morning, add the dissolved baking soda.
Shape and bake
Mix in the well-beaten eggs and enough flour to form a dough similar to biscuit dough.
Once the dough is light, work it down immediately.
Shape the dough into small rolls and place them in a horn mold.
Sprinkle the rolls with sugar and cinnamon, let them rise for 30 minutes.
Bake in a preheated oven at 350°F (175°C) until golden brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Yeast cake
- Ferments the batter, producing gas that makes the dough light and airy.
- Eggs
- Add structure and richness, helping the dough hold its shape when baked.
- Butter
- Adds fat for a tender crumb and rich flavor.
- Sugar
- Sweetens the dough and feeds the yeast, and browns the rolls on top.
- Flour
- Forms the batter and dough structure that traps gas and sets in the oven.
- Baking soda
- Reacts to add extra lift to the dough before shaping.
The step that matters
Work the dough down immediately once it is light. Once yeast has raised the dough, gently deflating it releases the trapped gas before shaping. Delaying this lets the dough over-proof, which can collapse it and leave a coarse, uneven texture.
