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 on the stove.
In a bowl, combine flour with salt, sugar, and yeast.
Add the milk mixture to the flour, ensuring it's not too hot.
Knead the dough thoroughly at night; in the morning, knead slightly.
Shape and rise
Roll out the dough and cut with a large biscuit cutter.
Spread a little butter on each roll and fold them together.
Let the rolls rise until very light.
Bake
Bake in a 400°F (200°C) oven, watching carefully to avoid over-baking.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

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 rolls their structure.
- Yeast
- Produces gas that makes the dough rise and become light.
- Lard
- Adds fat that tenderizes the crumb and softens the texture.
- Milk
- Provides moisture and richness that help the dough stay soft.
- Sugar
- Feeds the yeast and adds a little sweetness and browning.
The step that matters
Adding the milk mixture to the flour. If the milk is too hot it can kill the yeast, so the dough will not rise. The liquid should be warm, not hot, before it meets the yeast.
“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.
