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
Make the dough
Dissolve the yeast in warm water.
Mix in butter, scalded milk, sugar, and salt.
Add flour gradually to form a stiff dough.
Beat the egg white until stiff.
Fold the beaten egg white into the dough last.
Knead the dough vigorously until smooth.
Let it rise in a warm place until light.
Knead it down in the bowl.
Shape and bake
Take pieces the size of an egg.
Roll them into balls.
Shape the balls into strips about 9 inches long and ¾ inch thick.
Place them spaced apart on a baking tin.
Let them rise again.
Bake slowly until crisp and brittle.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Yeast
- Ferments and produces gas that makes the dough rise and turn light.
- Flour
- Forms the gluten network that gives the stiff dough its structure.
- Egg white
- Beaten stiff and folded in, it adds lift and an airy, light crumb.
- Butter
- Adds fat that tenderises the crumb and adds richness.
- Milk
- Adds moisture, milk solids and sugars that enrich flavour and browning.
- Sugar
- Feeds the yeast and adds sweetness and browning in the baked sticks.
The step that matters
Fold the beaten egg white in last. Folding gently keeps the air whipped into the egg white, so the dough stays light. Stirring or overworking it would deflate the foam and make the sticks denser.
“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.
