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.
Prepare the dough
Scald the milk with the lard in it over low heat.
Mix the flour, sugar, and yeast together in a bowl.
Add the warm milk mixture to the flour mixture, ensuring it's not too hot.
Knead the dough thoroughly at night and slightly the next morning.
Shape and bake
Roll out the dough to 1 inch thick and cut with a large biscuit cutter.
Spread a little butter on each roll and fold them over.
Let the rolls rise until very light, then bake in a 400°F (200°C) oven.

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 structure to hold its shape.
- Yeast
- Produces gas as it ferments, making the dough rise and become light.
- Milk
- Adds moisture and softness to the dough, and its sugars help browning.
- Lard
- Adds fat that tenderizes the crumb and keeps the rolls soft.
- Sugar
- Feeds the yeast and adds sweetness and browning to the crust.
The step that matters
Adding the warm milk mixture to the flour mixture. If the liquid is too hot it can kill the yeast, so the dough will not rise properly. The milk should be warm, not hot, before it is combined.
“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.
