Why it works: Milk and flour 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 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).
Make the batter
In a mixing bowl, combine the egg, milk, flour, and salt, then mix until smooth.
Bake
Fill a gem pan or buttered cups half full with the batter.
Bake until puffed and golden.

Milk and flour 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
- Egg
- Adds structure and helps the batter set around the steam as it bakes.
- Milk
- Adds moisture, which turns to steam in the oven and helps lift the batter.
- Flour
- Provides the structure that holds the puffed walls in place.
The step that matters
Fill the cups half full. Popovers rise by steam and need room to climb the sides of the cup. Half-full cups leave space for the batter to expand without spilling over, while overfilling can keep the walls from setting properly.
“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.
