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 ↓
Cinnamon Pie
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.
Make the filling
Melt the butter and sugar together in a saucepan.
In a bowl, beat the egg yolks, cinnamon, and cornstarch with the milk.
Combine the melted butter mixture with the egg mixture and bring to a boil.
Bake and serve
Pour the filling into a pie crust and top with beaten egg whites.
Bake in the oven at 350°F (175°C) until the top is lightly browned.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Yolks thicken the filling and whites form a light topping that browns in the oven.
- Sugar
- Adds sweetness and helps give the filling its body and browned top.
- Milk
- Provides the liquid base that the eggs and starch set into a custard.
- Butter
- Adds richness and fat, giving the filling a smooth, tender texture.
- Cornstarch or flour
- Thickens the liquid filling so it sets firmly when heated.
The step that matters
Bring the filling to a boil. Cornstarch needs to reach a boil to fully thicken. Heating egg yolks too quickly, or stopping early, can leave the filling thin or grainy.
“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.
