Why it works: Milk and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Chocolate Loaf Cake
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 chocolate mixture
Mix the grated chocolate with the milk and the yolk of one egg in a saucepan over low heat until melted and smooth.
Remove from heat and let cool.
Make the batter
In a bowl, beat the remaining egg whites until stiff.
In another bowl, cream the butter and sugar together.
Add the melted chocolate mixture and baking soda dissolved in a little water to the creamed mixture.
Gradually add flour until the batter is smooth and pourable.
Gently fold in the beaten egg whites.
Bake
Pour the batter into a greased loaf pan and bake at 350°F (175°C) until a toothpick comes out clean.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Yolk enriches the chocolate mixture while whipped whites add lift and a light crumb.
- Butter
- Creaming with sugar traps air and adds fat for a tender texture.
- Sugar
- Creams with butter for structure and adds sweetness and browning.
- Baking soda
- Reacts with the batter to produce gas that helps the cake rise.
- Flour
- Provides the structure that sets the cake as it bakes.
- Chocolate
- Adds the main flavor and deep color to the cake.
The step that matters
Folding in the beaten egg whites. Egg whites hold air only when whipped stiff; stirring them in vigorously knocks out that air, so fold gently with a spatula to keep the batter light and well risen.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
