Why it works: Milk and flour are a kitchen classic. They rank in the top 14% of all ingredient pairs, and 78,219 recipes mention both. Both carry isobutyraldehyde, which smells malty, green. 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
Scald the milk with the lard in a saucepan over medium heat.
In a large bowl, combine flour, salt, sugar, and yeast.
Add the warm milk mixture to the dry ingredients, mixing until combined.
Knead the dough thoroughly at night.
In the morning, knead slightly.
Shape and bake
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 light, then bake in a 400°F (200°C) oven.

Milk and flour share little aroma chemistry, yet 78,219 recipes mention both: they likely work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Yeast
- Ferments the dough so the rolls rise and become light.
- Lard
- Adds fat for a tender crumb and soft texture.
- Milk
- Provides moisture and richness to the dough.
- Flour
- Forms the gluten structure that holds the rolls together.
- Sugar
- Adds sweetness and helps the yeast ferment and the crust brown.
The step that matters
Kneading the dough at night and again in the morning. Thorough kneading develops gluten so the dough can trap gas from the yeast. Kneading the dough slightly in the morning keeps that structure without toughening the rolls.
“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.
