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 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare the batter
Preheat the oven to 400°F (200°C).
In a large bowl, whisk together the eggs and milk.
Gradually add the flour, mixing until smooth.
Stir in the melted butter and salt.
Bake
Pour the batter into greased popover pans.
Bake for 30-35 minutes until puffed and golden.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Flour and butter 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 protein that set the walls as the batter puffs.
- Flour
- Forms the gluten network that holds the risen shell in shape.
- Milk
- Adds moisture that turns to steam in the hot oven, helping the popovers rise.
- Butter
- Adds fat that contributes richness and tenderness to the crust.
The step that matters
Pour the batter into hot, greased pans. The batter must go into hot greased pans so the outside sets quickly while steam pushes it upward. A cold or poorly greased pan slows that start and can stop the popovers from rising tall.
Swap the walnut
How well each one fits the dish's main ingredients (egg, flour, milk, butter):
- Almondfits better
- Walnutthe original
- Pecansfits about as well
- Milletfits about as well
Fit is the average pairing score against egg, flour, milk, butter. Candidates are from the same food group and used in at least 100 recipes.
“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.
