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 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).
Grease a large puff pan or small pans and heat them until very hot.
Make and bake the batter
In a bowl, stir together the water, milk, salt, and egg yolks into the flour until smooth.
Gently fold in the beaten egg whites until well combined.
Pour the batter into the pans and bake for 15 to 30 minutes, depending on the size.

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
- Eggs
- Whites trapped with air and folded in lift the batter, while yolks add richness and structure.
- Flour
- Sets during baking to form the cake's structure as the steam-driven puff expands.
- Milk
- Adds moisture and browning sugars that help the cakes brown and taste richer.
- Water
- Turns to steam in the hot pan, driving the cakes up and creating their hollow interior.
The step that matters
Heating the pans until very hot before adding the batter. A very hot pan and oven create a burst of steam the moment batter hits the surface. This sudden expansion lifts the batter into a hollow puff; cool pans let it spread and sink instead.
