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 ↓
Puffs, or Pop-overs
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Mix the batter
Preheat the oven to 350°F (175°C).
In a large bowl, whisk together the milk, eggs, flour, and salt until smooth.
Fill cups or muffin tins about half full with the batter.
Bake and stand
Bake for 30 minutes.
Leave the oven door open and let the puffs stand for another 30 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.

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
- Flour
- Provides the structure that lets the batter hold its shape as it rises.
- Eggs
- Set the structure and help the batter puff as steam expands.
- Milk
- Adds moisture, creating the steam that lifts the batter.
The step that matters
Fill the cups about half full. The thin batter rises high in the oven by expanding with steam. Filling it only halfway leaves room for that rise, while overfilling can make it spill over or bake unevenly.
“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.
