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).
Grease and heat roll pans or deep 'Gem' pans.
Make the batter
Beat the eggs separately, adding the whites last.
Combine the milk, flour, and salt with the beaten eggs and mix well.
Bake
Fill the pans halfway with batter and bake immediately.

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
- Eggs
- Provides structure and, when beaten, air that helps the popovers rise.
- All-purpose flour
- Forms the gluten network that sets the walls around the steam.
- Milk
- Adds moisture that turns to steam, lifting the batter as it bakes.
The step that matters
Fill the hot pans and bake immediately. The pans must be hot and the batter must go in at once. The heat turns the liquid to steam on contact, which lifts the batter quickly. A cold pan or a delay lets the batter lose that steam before the walls set, so the popovers stay 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.
