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 very 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 pans well.
Make the batter
Beat the eggs until light and fluffy.
Mix the beaten eggs with the milk and salt.
Gradually pour the milk mixture over the flour while stirring until smooth.
Fill the greased pans about half full.
Bake
Bake in the hot oven for about 25 minutes.

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
- Provide structure and lift, setting the batter's walls as steam expands it.
- Flour
- Forms the gluten network that holds the risen batter walls together.
- Milk
- Adds moisture that turns to steam in the oven, helping the popovers rise.
The step that matters
Fill the pans about half full and keep the oven hot. Batter needs room to climb the pan sides as steam expands it. Overfilling blocks the rise, and a cool oven lets steam escape before the walls set, so popovers collapse or stay dense.
