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 says “a quick 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).
Make the batter
In a bowl, beat the egg until very light.
Add the milk and salt, and mix well.
Gradually stir in the pastry flour until smooth.
Bake
Pour the batter into gem pans.
Bake in the preheated oven 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
- Beaten egg adds structure and helps the batter rise and set around the steam.
- Milk
- Liquid that hydrates the flour and turns the batter into a pourable mixture that steams in the oven.
- Pastry flour
- Provides the starch and gluten that give the popovers their structure as they set.
The step that matters
Keep the oven preheated and do not open the door while baking. A very hot oven creates the steam that lifts the batter quickly. Opening the door early lets heat escape, so the batter may not puff and can collapse before the structure sets.
“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.
