Why it works: Flour and milk are a kitchen classic. They rank in the top 14% of all ingredient pairs, and cooks put them together in 78,219 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Plum 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
Preheat the oven to 350°F (175°C).
Make the batter
In a large bowl, mix the flour and sultanas.
Beat the eggs and add them to the mixture.
Add a little milk to achieve a smooth batter.
Bake
Pour the batter into a greased cake pan.
Bake for about 1 hour or until a skewer comes out clean.

Flour and milk barely smell alike, yet cooks put them together in 78,219 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Provides the structure that holds the cake together as it bakes.
- Eggs
- Bind the batter and add structure and richness as they set.
- Sultanas
- Add sweetness and a chewy texture throughout the cake.
- Milk
- Adds moisture and loosens the batter so it spreads smoothly.
The step that matters
Add the milk gradually. Adding liquid a little at a time helps the batter blend smoothly without lumps. Lumps left in the batter can bake into uneven pockets of flour in the finished cake.
