Why it works: Milk and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓

Directions
The book says “a hot 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 sifted flour and salt.
Gradually add the milk while stirring constantly to form a smooth batter.
Stir in the beaten eggs and melted butter.
Beat the mixture for 2 minutes using an egg beater.
Bake
Pour the batter into hot buttered cups or iron gem pans.
Bake in a preheated oven at 400°F (200°C) for 30 to 35 minutes.

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, helping the batter puff and set around the steam.
- All-purpose flour
- Forms the gluten network that holds the risen walls in shape.
- Milk
- Supplies the liquid that turns to steam and moisture, adding tenderness and browning.
- Melted butter
- Adds fat for richness and helps the popovers brown and release from the pan.
The step that matters
Preheat the oven and pans until hot before pouring in the batter. The batter needs an immediate burst of heat so its liquid turns to steam quickly, pushing the walls up before they set. A cold pan or oven lets the batter spread and sit flat instead of rising high.
