Why it works: Milk and vanilla are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 19,187 recipes. Both carry ethyl caproate, which smells fruity, apple peel. 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. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Make the batter
Preheat the oven to 350°F (175°C).
Cream the butter and sugar together until light and fluffy.
Add the eggs and mix well.
In a separate bowl, combine the flour, baking soda, and cream of tartar.
Gradually add the dry ingredients to the butter mixture, alternating with the milk.
Pour the batter into a pie crust and bake for 25-30 minutes.
Make the frosting and finish
For the frosting, beat the egg whites until stiff peaks form.
Gradually add the sugar and continue beating until glossy.
Fold in the chocolate and vanilla extract.
Spread the frosting over the cooled pie.

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 trap air and add richness and a tender texture.
- Flour
- Provides the structure that holds the cake-like pie together as it sets.
- Eggs
- Bind the batter and add structure and richness as they set in the oven.
- Baking soda
- Reacts with the acid in the cream of tartar to release gas, helping the pie rise.
- Cream of tartar
- Acidic partner to baking soda, producing gas for lift and stabilizing the mixture.
- Egg whites
- Whipped to stiff peaks to form a light, stable foam for the frosting.
The step that matters
Beating the egg whites to stiff peaks. Egg whites must be beaten until stiff peaks form, as their trapped air gives the frosting its volume and lightness. Underbeaten whites stay runny and deflate, while overbeaten whites turn dry and grainy. Adding sugar gradually helps stabilize the foam.
