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 ↓

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.
Prepare the batter
Preheat the oven to 350°F (175°C).
Beat the eggs until very light using a Dover egg-beater.
Mix the salt and flour together.
Gradually add the milk to the flour mixture to avoid lumps, beating steadily.
Add the beaten eggs and mix well.
Finally, add the melted butter and mix to combine.
Bake and serve
Pour the batter into well-buttered earthen cups, filling them two-thirds full.
Place the cups on a baking sheet and bake on the oven floor for 45 minutes.
Do not open the oven for at least 25 minutes to ensure they puff up.
After baking, let them dry out for 5 minutes with the oven door partly open.

Butter and flour barely smell alike, yet cooks put them together in 124,287 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 as the beaten eggs set the batter during baking.
- Pastry flour
- Forms the gluten framework that holds the batter's shape as it bakes.
- Milk
- Adds moisture that turns to steam, helping the popovers rise.
- Melted butter
- Adds richness and flavour and helps the crust brown.
The step that matters
Do not open the oven for at least 25 minutes. Opening the oven drops the temperature and releases the steam that drives the rise, so the popovers may collapse before the structure sets.
“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.
