Why it works: Milk and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓

Directions
The book says “a very quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure. The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare
Preheat the oven to 400°F (200°C).
In a bowl, combine milk, flour, beaten egg, melted butter, and salt.
Pour 1 tablespoon of the batter into each cup of a muffin tin.
Bake
Bake for about 20-25 minutes until puffed and golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Provides structure and protein that sets the walls as the popover rises.
- All-purpose flour
- Forms the gluten network that holds the risen shell in shape.
- Milk
- Adds moisture that turns to steam, pushing the batter up as it bakes.
- Butter
- Adds fat for richer flavor and a more tender, golden crust.
The step that matters
Bake in a hot oven until puffed and golden. The batter's moisture turns to steam in a hot oven, which lifts the walls and creates the hollow center. Thin walls need the heat to set before they collapse, so the oven must be fully preheated before the tin goes in.
