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 ↓
Cheese Tartlets
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
Roll out the puff pastry thinly.
Butter nine or ten small patty pans.
Cut the pastry into circles with a notched cutter.
Line the pans with the pastry circles.
Make the filling
In a small saucepan, melt the butter and flour over low heat, stirring until combined.
Add the milk and stir until the mixture boils and thickens, then remove from heat.
Incorporate the egg yolks one at a time, mixing thoroughly after each addition.
Add the salt, pepper, and cheese, mixing well.
Gently fold in the stiffly beaten egg whites.
Bake and serve
Spoon the mixture into the prepared pans and bake in a 350°F (175°C) oven for about 15 minutes until risen.
Serve immediately.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Enriches the base and, with flour, forms the roux that thickens the filling.
- Flour
- Thickens the melted butter and milk into a smooth, stable sauce base.
- Milk
- Forms the liquid that the roux thickens into a creamy custard base.
- Eggs
- Yolks enrich and set the filling; beaten whites lighten it and help it rise.
- Parmesan cheese
- Adds savoury, salty flavour and helps the filling set as it bakes.
The step that matters
Gently fold in the stiffly beaten egg whites. Egg whites hold air bubbles that make the filling rise. Vigorous stirring deflates them, so the tartlets bake flat and dense.
“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.
