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
Preheat the oven to 400°F (200°C).
Grease the cups of a popover pan.
Make and bake
In a bowl, mix flour, milk, salt, and eggs until smooth.
Fill each cup about one-third full with the batter.
Bake without opening the oven until the sides are brown.

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
- All-purpose flour
- Provides the protein and starch that form the hollow, sturdy walls of the popover.
- Large eggs
- Add structure and help the batter set around the steam as it puffs.
- Sweet milk
- Supplies moisture that turns to steam in the hot oven, driving the rise.
The step that matters
Bake without opening the oven. Opening the door lets heat and steam escape and drops the temperature. The batter needs sustained high heat to puff quickly before the walls set, so a sudden drop can leave popovers flat.
“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.
