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 ↓
Excellent Pop-Over
a dozen cupsIngredients
Directions
The book says “a moderately hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 400°F (200°C).
Butter a dozen stone or earthenware cups and arrange them in an old dripping pan.
Make the batter
In a mixing bowl, combine the sifted flour, sugar, and salt.
Beat the eggs until very light, then add the milk.
Pour the egg and milk mixture into the flour, starting with half, and beat until smooth and light, about 5 minutes.
Bake
Pour the batter into the prepared cups and bake for 50 minutes until they have increased to four times their original size.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Provide structure and lift as they expand with steam during baking, letting the popovers rise.
- Flour
- Forms the gluten network that holds the batter's shape as it puffs and sets.
- Milk
- Adds moisture that turns to steam in the oven and helps the batter set into a tender crumb.
The step that matters
Beat the batter until smooth and light. Beating incorporates air and develops the gluten network that lets the batter stretch. Under-beaten batter, or batter left lumpy, may not rise well and can stay dense.
