Why it works: Flour and milk 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 gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the dough
Boil the milk and melt the lard in it.
Sift the flour into a deep dish and make a hole in the center.
Add the yeast, sugar, and salt into the hole, then pour in the cooled milk.
Let the mixture stand without mixing overnight.
Shape and bake
In the morning, mix and mold the dough.
Let it rise, then mold again and roll to ½ inch thick.
Cut with a cake cutter, fold over, let rise again, and bake at 400°F (200°C) until light.

Flour and milk 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
- Flour
- Forms the gluten structure that traps gas and gives the rolls their chewy crumb.
- Yeast
- Produces carbon dioxide during fermentation, making the dough rise and become light.
- Milk
- Adds moisture and milk proteins that soften the crumb and aid browning.
- Lard
- Adds fat that tenderizes the crumb and keeps the rolls soft.
- Sugar
- Feeds the yeast and promotes browning in the oven.
The step that matters
Letting the mixture stand overnight. The long, slow rest without mixing lets the yeast ferment gradually, developing flavor and gluten strength. Disturbing the mixture or rushing this rise can leave the rolls dense.
“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.
