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. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare
Preheat the oven to 400°F (200°C) and heat a gem pan.
Make the batter
In a mixing bowl, combine the egg, flour, milk, and salt. Mix until smooth.
Pour the batter into the heated gem pan.
Bake
Bake until puffed and golden, about 20-25 minutes.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

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
- Egg
- Adds structure and richness, helping the batter set around the steam as it bakes.
- All-purpose flour
- Provides the gluten network that holds the risen shell together.
- Milk
- Supplies moisture that turns to steam, pushing the batter up to puff and adding browning from milk sugars.
The step that matters
Pour the batter into the heated gem pan. The pan must be hot before the batter goes in. The sudden heat turns the moisture to steam quickly, which lifts the batter into a tall, hollow shell. A cold pan gives a flat, dense result.
