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 ↓
Eggless Chocolate 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.
Make the batter
Melt chocolate and shortening together.
Add sugar to the melted mixture and stir well.
Dissolve baking soda in water and mix it into the batter.
Gradually add sour milk and flour, mixing until smooth.
Add vanilla to taste.
Bake
Pour the batter into a greased cake pan.
Bake at 350°F (175°C) for 30-35 minutes or 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
- Baking soda
- Reacts with the sour milk to produce gas, helping the cake rise and turn light.
- Sour milk
- Its acidity activates the baking soda and adds moisture and tenderness to the crumb.
- Flour
- Provides the structure that sets the cake as it bakes.
- Shortening
- Adds fat for a tender texture and moisture in the crumb.
- Chocolate
- Supplies the chocolate flavour and some richness to the batter.
The step that matters
Mix in the baking soda and sour milk promptly. Baking soda starts reacting as soon as it meets the acidic sour milk, so gas forms early. Delaying the bake or mixing too long can let bubbles escape, leaving a denser cake.
