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
Beat the eggs separately until well combined.
Add the egg whites last and mix everything together thoroughly.
Pour the batter into mold pans or rings.
Bake
Bake until puffed and golden brown.

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
- Flour
- Provides the structure that holds the risen popover walls in shape.
- Eggs
- Add structure and help the batter puff as steam expands during baking.
- Milk
- Adds moisture and helps the batter cook into a tender interior.
The step that matters
Preheat the oven fully. Popovers rise because the thin batter hits high heat and its water turns to steam, which lifts the walls. A fully hot oven at the start creates this burst of steam quickly. A cool oven lets the batter spread and fail to puff.
