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
Make the dough
Dissolve yeast cakes in milk.
When lukewarm, add salt and one cup flour.
Cover and let rise until very light.
Add sugar, butter, eggs unbeaten, and flour enough to handle.

Let rise again.
Bake for twenty minutes.
When cold, cut diagonally into one-half inch slices.
Brown evenly in oven.
Nutrition, whole recipe (rough)

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
- Yeast cakes
- Ferment the dough so it rises and becomes light before baking.
- Eggs
- Add structure and richness to the dough as it sets in the oven.
- Butter
- Adds fat for a tender crumb and rich flavour.
- Sugar
- Adds sweetness and helps the dough brown in the oven.
- Flour
- Forms the gluten network that gives the dough its structure.
The step that matters
Let the dough rise until very light. Yeast needs time to produce enough gas to lighten the dough. Underproofed dough bakes dense, while the rise before shaping and the second rise give the rusks their open, airy crumb.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
