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.
Prepare and bake the crusts
Preheat the oven to 350°F (175°C).
In a bowl, mix sugar, flour, milk, butter, eggs, cream of tartar, and baking soda until smooth.
Pour the mixture into Washington pie tins and bake until golden.
Make and add the filling
For the filling, melt the chocolate and mix with powdered sugar, egg yolks, and boiling milk.
Pour the filling into the baked pie crusts.
Frost and brown
Whip the egg whites until stiff, then frost the pies and brown the tops.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Provides the structure that holds the crust together as it bakes.
- Eggs
- Bind the batter and add structure, while the yolks thicken the filling.
- Butter
- Adds fat for a tender crust and rich flavor.
- Baking soda
- Reacts with the acid in the batter to release gas and help the crust rise.
- Cream of tartar
- Acts as the acid that reacts with baking soda to lift the batter.
- Chocolate
- Gives the filling its main flavor and firms as it cools.
The step that matters
Whipping the egg whites until stiff. Egg whites must be beaten until they hold firm peaks, because under-whipped foam stays runny and collapses. Stiff whites also brown well and hold their shape on top of the pie.
