Why it works: Flour and milk are a kitchen classic. They rank in the top 14% of all ingredient pairs, and cooks put them together in 78,219 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

Ingredients
Directions
The book says “a quick oven”. The 400°F in the steps is the modern equivalent, not the book's own figure.
Prepare the batter
Grease the pans and place them in a hot oven (400°F / 200°C) to heat.
Beat the eggs until very light, without separating them.
Add the milk and salt, then gradually pour this mixture onto the flour while stirring continuously.
Strain the batter through a sieve to remove lumps.
Bake
Quickly take the hot pans from the oven, fill them half full with the batter, and return them to the oven.
Bake for 25 minutes.

Flour and milk barely smell alike, yet cooks put them together in 78,219 recipes: they 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
- Provides the structure that holds the risen batter walls in place.
- Eggs
- Add structure and help the batter rise as steam expands during baking.
- Milk
- Supplies moisture, which turns to steam and lifts the batter as it bakes.
The step that matters
Filling the hot pans quickly. Batter poured into hot pans starts setting and steaming right away, lifting the walls. If the pans cool while you work, the steam is weaker and the popovers rise poorly.
“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.
