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 hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 400°F (200°C).
In a bowl, mix the flour, milk, egg yolks, and salt until smooth.
Butter six earthen cups and place them in the oven to heat.
Bake
Beat the egg whites until stiff peaks form, then quickly fold them into the batter.
Pour the batter into the hot buttered cups.
Bake in the hot oven until they rise and are brown on the sides, about 20-25 minutes.
Serve
Serve immediately, with butter or maple syrup.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- All-purpose flour
- Provides the structure that holds the risen walls of the popover.
- Milk
- Supplies moisture that turns to steam, helping the batter puff in the oven.
- Egg yolks
- Add richness and help bind the batter into a smooth, tender mixture.
- Egg whites
- Whipped into stiff peaks, they trap air and give the popovers their rise.
The step that matters
Folding in the egg whites. Whites must be beaten to stiff peaks and folded in quickly so the air bubbles are not lost. The air and steam from the hot cups drive the rise.
“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.
