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 ↓
Cream 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
In a saucepan, boil the sweet milk.
In a bowl, mix the egg yolks, cornstarch, sugar, and butter.
Stir the mixture into the boiling milk until thickened.
Add lemon flavor or coconut if desired.
Top and bake
Whip the egg whites with powdered sugar until stiff peaks form.
Spread the whipped egg whites over the pie filling.
Brown the pie in a 350°F (175°C) oven.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Thicken the custard and add richness and colour to the filling.
- Cornstarch
- Thickens the hot milk into a smooth, sliceable custard as it cooks.
- Egg whites
- Whipped into stiff peaks to form the airy topping that browns in the oven.
- Sugar
- Sweetens the filling and helps stabilise the whipped egg white topping.
- Sweet milk
- Forms the liquid base of the filling, which thickens when starch is added.
The step that matters
Stir the mixture into the boiling milk until thickened. Cornstarch only thickens fully when heated, and the yolks can scramble if the mixture is added too cold or stirred poorly. Constant stirring keeps the custard smooth and evenly thickened.
Swap the lemon
The recipe marks lemon as optional. How well each one fits the dish's main ingredients (egg, sugar, butter, walnut, milk):
- Vanillafits better
- Figfits better
- Coconutfits better
- Lemonthe original
Fit is the average pairing score against egg, sugar, butter, walnut, milk. Candidates are from the same food group and used in at least 100 recipes.
