Why it works: Butter and milk 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.
Prepare the dough
Rub the flour and butter together.
Boil the milk.
Cool the milk the night before.
Make a well in the flour.
Pour in the milk.
Add the sugar, salt, beaten egg, and yeast without stirring.
Let the mixture stand overnight.
In the morning, stir.
Knead.
Let rise until near tea time.
Shape and bake
When very light, roll out.
Cut with a biscuit cutter.
Put a little melted butter on half of each biscuit.
Fold over.
Place the rolls in a pan about 3 inches apart.
Let rise.
Bake 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 structure that gives the rolls their framework and chew.
- Yeast
- Produces gas as it ferments, causing the dough to rise and turn light.
- Milk
- Hydrates the flour and adds moisture and softness to the crumb.
- Egg
- Adds richness and structure, helping the dough hold its shape and softness.
- Butter
- Adds fat for tenderness and flavor, and browns the tops of the rolls.
- Sugar
- Feeds the yeast and adds a touch of sweetness and browning.
The step that matters
Letting the dough rise until very light. Yeast needs time to ferment and build gas bubbles; rolling or baking before the dough is fully risen leaves rolls dense and heavy.
“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.
