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.
Prepare 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, which has been mixed with the baking soda and cream of tartar.
Bake and make the filling
Bake for 50 minutes.
For the filling, mix the chocolate and sugar together.
Slowly add the boiling milk and yolks, simmering for about 10 minutes.
Let the filling cool completely before adding it to the pie.

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 creaming it with sugar traps air for a lighter texture.
- Eggs
- Add structure and richness as they set, binding the batter together.
- Flour
- Provides the structure that holds the pie together as it bakes.
- Baking soda
- Reacts with the cream of tartar to help the batter rise.
- Cream of tartar
- Acidifies the batter so it reacts with baking soda to lighten the texture.
- Chocolate
- Gives the filling its chocolate flavour and deep colour.
The step that matters
Let the filling cool completely before adding it to the pie. A hot filling softens the crust and can keep the custard from setting firmly, so cooling it fully helps the pie hold its shape when cut.
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.
