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.
Make the dough
Sift the flour into a bowl and make a hole in the middle.
Add the lard, sugar, warm milk, yeast, and salt into the hole.
Let the mixture stand in a warm place without stirring until light.
Stir to form a soft dough, adding more flour if necessary.
About two hours before serving, work out the dough with a little more flour.
Shape and bake
Roll out the dough to about ½ inch thick and cut with a biscuit cutter.
Lightly butter the cut dough, fold over, and place in pans a little apart.
Let the rolls rise until tea time and bake in a preheated oven at 400°F (200°C).

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 dough its structure and chew.
- Yeast
- Produces gas as it ferments, making the dough rise and become light.
- Lard
- Adds fat that tenderises the crumb and keeps the rolls soft.
- White sugar
- Feeds the yeast and adds sweetness and browning in the oven.
- Sweet milk
- Provides moisture and richness, helping the dough become soft and supple.
The step that matters
Let the mixture stand without stirring until light. The yeast needs warmth and time to ferment before the dough is mixed further. Stirring too early knocks out the gas bubbles being trapped, so the rolls rise less and turn out denser.
“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.
