Why it works: Butter and milk 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.
Melt and cream
Dissolve the chocolate in ½ cup of milk.
Mix in ½ cup of sugar.
Beat the egg yolks until stiff and frothy.
Cream the butter with 1 cup of sugar until light and fluffy.
Add the beaten yolks to the butter mixture.
Make the batter
Fold in the beaten egg whites.
Stir in the dissolved chocolate mixture, remaining milk, flour, and baking powder.
Pour the batter into a loaf pan.
Bake
Bake at 350°F (175°C) for 30 to 40 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Yolks enrich and add richness, while whites whip into air that gives the cake lift and structure.
- Butter
- Creaming with sugar traps air and gives the cake a tender, rich crumb.
- Granulated sugar
- Sweetens the cake and, creamed with butter, helps make the crumb tender.
- All-purpose flour
- Its proteins form the gluten network that gives the cake its set structure.
- Baking powder
- Releases gas in the batter and heat, causing the cake to rise.
- Chocolate
- Provides the main chocolate flavour and a deep brown colour.
The step that matters
Fold in the beaten egg whites. Folding gently keeps the air beaten into the whites, which lifts the cake. Stirring hard or over-mixing deflates the foam, leaving a dense loaf.
