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
Preheat the oven to 350°F (175°C).
Make the batter
Melt the butter and mix it with the milk.
In a bowl, beat the eggs and then add the milk and butter mixture.
Gradually stir in the flour until smooth.
Bake and serve
Pour the mixture into buttered cups.
Bake until puffed and golden.
Serve with a rich sauce.

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, setting the batter as it bakes and helping it puff.
- Flour
- Forms the gluten network that gives the cake its body and holds its shape.
- Milk
- Adds moisture that turns to steam in the oven, helping the cake rise and puff.
- Butter
- Adds fat for richness and tenderness, and helps the cake brown.
The step that matters
Bake until puffed and golden. Eggs and flour set around the steam inside the cups, causing the puff. Pulling the cakes too early leaves them collapsing, while overbaking dries them out.
“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.
