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.
Make the batter
In a bowl, mix the flour and salt.
Slowly add 1 cup of milk, stirring until a smooth paste forms.
Add another cup of milk and the beaten egg, then beat well.
Bake
Pour the mixture into buttered gem pans or earthen cups.
Bake in a 400°F (200°C) oven for 30 minutes or until golden brown.

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 structure that holds the risen batter walls together as they set.
- Milk
- Supplies the liquid that turns to steam in the oven, driving the rise.
- Egg
- Adds structure and richness, helping the batter set around the steam.
The step that matters
Bake without opening the oven door. Popovers rise by steam expanding the batter before its walls set. Opening the oven early lets heat escape, so the batter can collapse and the popovers may stay 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.
