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 quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the dough
Melt the butter in the warm milk.
Add the sugar, salt, and flour to the mixture.
Let the mixture rise overnight.
Dissolve the baking soda in water.
Add the dissolved baking soda to the mixture.
Mix in enough flour to achieve a soft dough similar to biscuit dough.
Shape the rolls
Roll out the dough to about ¼ inch thick.
Cut the dough with a large round cutter.
Spread soft butter on top of each cut piece.
Fold each round in half.
Place the folded rolls apart on a baking sheet.
Cover the rolls.
Rise and bake
Let the rolls rise near a warm place for 15-20 minutes.
Bake the rolls in a preheated oven at 400°F (200°C) until golden.

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 gives the dough its structure and chew.
- Yeast
- Ferments the dough, producing gas that makes the rolls rise and turn airy.
- Butter
- Adds fat for tender texture and rich flavor in the dough and on the rolls.
- Milk
- Provides moisture and softness, and helps the dough brown in the oven.
- Sugar
- Feeds the yeast and adds sweetness and browning to the crust.
- Baking soda
- Reacts with the dough's acidity to add lift and a tender crumb.
The step that matters
Let the mixture rise overnight. The yeast needs time to ferment the dough fully, which builds flavor and the gas that lifts the rolls. Too short a rise leaves the rolls dense.
