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 ↓
Dark Chocolate Loaf Cake
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.
Prepare
Melt the chocolate with ½ cup milk in a double boiler and let it cool.
Cream the butter and sugar together.
Mix and bake
Add the egg yolk, eggs, melted chocolate mixture, and other ingredients to the creamed mixture.
Combine everything well and pour into a loaf pan.
Bake in a moderate oven at 350°F (175°C) until done.
Frosting
Use the egg white to make frosting.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Forms the cake's structure as its proteins set during baking.
- Eggs
- Bind the batter and add structure, richness, and moisture to the crumb.
- Butter
- Adds fat that tenderizes the crumb and carries flavor.
- Sugar
- Adds sweetness and helps tenderize the crumb while creaming with butter.
- Baking soda
- Reacts with acidity in the batter to release gas, helping the cake rise.
- Chocolate
- Contributes deep chocolate flavor, color, and some richness to the batter.
The step that matters
Let the melted chocolate cool before combining. Adding hot melted chocolate to the eggs and creamed butter can cause the eggs to scramble and the butter to melt or separate, leading to a coarse, greasy batter. Cooling it first keeps the emulsion smooth.
