Why it works: Milk and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and 81,283 recipes mention both. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Parker House 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
Add butter, sugar, and salt to the scalded milk.
Let the mixture cool until lukewarm.
Dissolve the yeast in the lukewarm water.
Add the dissolved yeast to the milk mixture along with 3 cups of flour.
Beat the dough thoroughly.
Cover the dough.
Let the dough rise until light.
Cut down the dough.
Add enough of the remaining flour to knead.
Let the dough rise again in a warm place.
Shape the rolls
Knead the dough on a slightly floured board.
Pat the dough.
Roll out the dough to ⅓ inch thickness.
Shape into rounds using a biscuit cutter.
Dip the handle of a knife in flour.
Make a crease through the middle of each piece.
Brush one half of each piece with melted butter.
Fold the pieces.
Press the edges together.
Bake
Place the rolls in a greased pan one inch apart.
Cover the rolls.
Let the rolls rise.
Bake in a hot oven at 400°F (200°C) for 12 to 15 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Forms the gluten network that traps gas and gives the rolls their structure.
- Yeast
- Produces gas as it ferments, causing the dough to rise and become light.
- Milk
- Adds moisture and richness, softening the crumb and promoting gentle browning.
- Butter
- Adds fat that tenderizes the crumb and gives the rolls a richer flavor.
- Sugar
- Feeds the yeast and promotes browning on the crust.
The step that matters
Let the dough rise until light, then again in a warm place. Yeast needs time and warmth to produce enough gas for a light, airy crumb. Rolls that rise too little stay dense, while over-proofing weakens the gluten and can cause collapse in the oven.
