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 ↓

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, cream together the butter and sugar.
Add the milk and mix well.
Gradually add flour to form a batter.
Stir in the yeast gently; do not beat after adding yeast.
Let the mixture rise until very light.
Add more flour if needed to achieve the right consistency.
Shape and bake
Shape into cakes and let them rise again.
Bake in a preheated oven at 350°F (175°C) until golden.

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
- Butter
- Adds fat that gives the rusk a rich, tender crumb and flavour.
- Sugar
- Adds sweetness and helps browning in the oven.
- Milk
- Adds moisture and softness to the dough.
- Flour
- Provides the structure that holds the batter and shaped cakes together.
- Yeast
- Produces gas during fermentation, which makes the dough rise and become light.
The step that matters
Stirring in the yeast gently. Yeast works by producing gas that gets trapped in the dough. Beating vigorously after the yeast is added knocks out these bubbles and can toughen the dough, so the rise becomes weaker and the texture denser.
