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 quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the dough
Rub together the flour, butter, and lard in a large bowl.
Make a hole in the center of the mixture.
Pour in the cold boiled milk, sugar, salt, and yeast.
Let the mixture stand overnight.
Beat the mixture well. Mix thoroughly.
Let it stand until noon.
Shape and bake
Roll out the dough and cut into cakes.
Butter each piece and fold them over.
Let the rolls stand until supper time.
Bake 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
- All-purpose flour
- Forms the gluten network that gives the rolls their structure.
- Butter
- Adds fat that tenderizes the crumb and carries flavor.
- Lard
- Adds fat that softens the crumb and keeps the rolls tender.
- Milk
- Provides moisture that hydrates the flour and helps form the dough.
- Sugar
- Feeds the yeast and adds sweetness and browning in the oven.
- Yeast
- Ferments the dough, producing gas that makes the rolls rise.
The step that matters
Letting the mixture stand overnight. Long fermentation lets the yeast develop flavor and gas slowly. Too little time leaves the rolls dense, while the dough needs its full rise before shaping.
