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 batter
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.
Stir in the flour, cream of tartar, and baking soda.
Pour the mixture 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, simmering for about 10 minutes.
Let the filling 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
- Creams with sugar to give the batter a light, tender texture and richness.
- Eggs
- Bind the batter and add structure as they set during baking.
- Flour
- Provides the main structure that holds the baked pie together.
- Baking soda
- Reacts with cream of tartar to produce gas that helps the batter rise.
- Cream of tartar
- Acidifies the batter so baking soda can react and lighten the texture.
- Egg yolks
- Thicken the filling as they cook and add richness and smoothness.
The step that matters
Slowly add the boiling milk and egg yolks. Adding hot milk to yolks too quickly can scramble them. Adding it slowly while stirring tempers the yolks so the filling thickens smoothly as it simmers.
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.
