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.
Make the batter
Preheat the oven to 350°F (175°C).
Cream together the sugar and butter.
Add the milk and mix well.
Sift the flour with the baking powder and gradually add to the mixture.
Incorporate the 5 eggs, leaving out the whites of 4.
Pour the batter into Washington pie tins to make three two-layer pies.
Make the frosting and assemble
Beat the reserved egg whites until stiff.
Melt the chocolate in a saucer over steaming water until creamy.
Mix the melted chocolate with the powdered sugar and vanilla.
Spread the frosting between the layers and on top of the pies.

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 add richness and a tender crumb.
- Eggs
- Add structure and richness to the batter as it sets in the oven.
- Egg whites
- Beaten until stiff to lighten the frosting and give it body.
- Flour
- Forms the main structure of the cake layers as it sets.
- Baking powder
- Releases gas in the batter, helping the layers rise.
- Chocolate
- Gives the frosting its chocolate flavor and color.
The step that matters
Beat the reserved egg whites until stiff. Egg whites only hold air when fully whipped and free of yolk or grease. Under-beaten or greasy whites collapse, leaving a dense, flat frosting.
