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
Scald the milk and pour it over the sugar, salt, and butter.
Allow it to cool, then add the yeast dissolved in lukewarm water.
Stir in 3 cups of flour and beat hard.
Cover and let rise until frothy.
Add the remaining 3 cups of flour and let rise again until doubled in size.
Shape the rolls
Place the dough on a floured surface and knead lightly.
Roll out to ½ inch thick and cut out rolls with a biscuit cutter.
Brush each roll with butter, fold, and press the edges together.
Place in a greased pan, 1 inch apart, and let rise until very light.
Bake
Bake in a hot oven at 400°F (200°C) for 15 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Milk
- Adds moisture and tenderness, and its milk solids help the crumb brown.
- Flour
- Forms gluten, the stretchy network that gives the rolls their structure.
- Yeast
- Produces carbon dioxide gas as it ferments, making the dough rise.
- Butter
- Adds fat that tenderizes the crumb and adds richness and flavor.
- Sugar
- Feeds the yeast and adds sweetness and browning in the baked crust.
The step that matters
Let the dough rise until doubled and the shaped rolls very light. Yeast gas expands the dough and sets its airy crumb. Underproofed rolls stay dense and tight, while overproofed ones may collapse or bake up flat.
“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.
