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 ↓

Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the chocolate custard
Cook chocolate and ¼ cup milk with the egg yolk until thick like custard. Set aside to cool.
Make the batter
Cream the shortening and add the sugar.
Combine the cooled chocolate mixture with the creamed shortening and sugar.
Dissolve the baking soda in ¾ cup milk and add it alternately with the flour to the mixture.
Fold in the beaten egg white.
Bake
Bake in two layers in a moderate oven at 350°F (175°C).

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Chocolate
- Gives the cake its deep chocolate flavor and dark color, and adds richness from its fat.
- All-purpose flour
- Provides the protein structure that holds the cake's crumb together as it bakes.
- Sugar
- Adds sweetness and helps keep the crumb soft and tender.
- Shortening
- Adds fat that tenderizes the crumb and carries flavor.
- Baking soda
- Reacts with the acidic components to release gas that helps the cake rise.
- Egg
- The yolk thickens the chocolate custard, and the beaten white adds lift and structure.
The step that matters
Cooking the chocolate custard. The egg yolk proteins set as they heat. Heating too quickly or too long can curdle the mixture into grainy lumps, so cook gently, stirring steadily, only until it thickens.
