Why it works: Butter and milk 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.
Prepare the batter
Preheat the oven to 400°F (200°C).
In a bowl, whisk together the eggs, flour, melted butter, milk, and salt until smooth.
Pour the mixture into a greased baking dish.
Bake and serve
Bake for 20 minutes until puffed and golden.
Serve as a dessert with lemon sauce.

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 puffs.
- Flour
- Gives the batter body so it holds its shape around the puffed centre.
- Milk
- Supplies the liquid that turns to steam in the oven, helping the puffs rise.
- Melted butter
- Adds richness and helps the puffs brown and taste savoury-sweet.
The step that matters
Bake until puffed and golden. The puff comes from steam forming quickly in a very hot oven, so the oven must be fully preheated and the batter should go in promptly. Pulling the dish too early leaves the centre wet and the puffs collapse as they cool.
