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 ↓

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).
In a bowl, combine the flour and salt.
Make the batter
In a separate bowl, beat the egg yolk and add part of the milk, stirring well.
Gradually mix in the remaining milk with the flour mixture.
In another bowl, beat the egg white until stiff peaks form, then fold it into the batter.
Bake
Grease gem pans and pour the batter into them.
Bake for 30 minutes until browned.

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 starch and gluten that give the popovers their structure as they rise.
- Egg
- The whites trapped as stiff peaks lift the batter and help it rise; the yolk adds richness.
- Milk
- Supplies the liquid that turns to steam in the hot oven, adding moisture and lift.
The step that matters
Folding in the egg white. Stiff whites hold air that gives the popovers their lift. Folding gently keeps that air in the batter, while vigorous stirring would deflate it and leave the 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.
