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 ↓
Chocolate 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 cake base
Preheat the oven to 350°F (175°C).
Beat the butter until light, then gradually add the sugar, beating until creamy.
Add the eggs and milk, mixing well.
In a separate bowl, combine the flour with the baking soda and cream of tartar, then stir into the mixture.
Pour the batter into a pie dish and bake for 50 minutes.
Make the filling
For the filling, mix the chocolate and sugar together.
Slowly add the boiling milk and egg yolks, stirring continuously.
Simmer the mixture for about 10 minutes until thickened.
Allow the filling to cool completely before using.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds fat and richness, and helps the batter turn light and tender when beaten.
- Eggs
- Provide structure and binding as the batter sets in the oven.
- Flour
- Forms the structure of the batter as it bakes.
- Baking soda
- Reacts with cream of tartar to produce gas that helps the batter rise.
- Egg yolks
- Thicken the filling as it heats and give it a smooth, rich texture.
- Chocolate
- Gives the filling its flavour and colour.
The step that matters
Simmering the filling. Egg yolks can curdle or scramble if the mixture overheats. Adding the boiling milk slowly and stirring constantly tempers the yolks, and gentle simmering lets the starch and yolk proteins thicken the filling smoothly.
Swap the nutmeg
How well each one fits the dish's main ingredients (butter, sugar, milk, flour, cream, egg, chocolate):
- Cinnamonfits about as well
- Nutmegthe original
- Gingerfits less well
- Jalapenofits less well
Fit is the average pairing score against butter, sugar, milk, flour, cream, egg, chocolate. Candidates are from the same food group and used in at least 100 recipes.
