Why it works: Flour and raisin match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 9,075 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Plum 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 batter
In a large bowl, cream the butter and sugar until smooth.
Add 2 eggs and beat for 5 minutes.
Repeat until all 12 eggs are added.
Gradually mix in a handful of flour.
Add the remaining flour and raisins.
Prepare the tin
Butter the cake tin.
Line the bottom with strong paper.
Brush the inside with melted butter.
Dust with powdered sugar and a little flour.
Bake
Pour the mixture into the tin.
Bake in a 350°F (175°C) oven for about 2 hours.

Flour and butter barely smell alike, yet cooks put them together in 124,287 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
- Butter
- Creams with the sugar to trap air and give the cake a tender, rich texture.
- Eggs
- Bind the batter and add structure and richness as the cake sets in the oven.
- Flour
- Provides the structure that holds the cake together as it bakes.
- Sultana raisins
- Add moisture and pockets of sweetness throughout the cake.
- Soft sugar
- Sweetens the batter and, creamed with butter, helps give a light crumb.
The step that matters
Adding the eggs one at a time while beating. Adding eggs gradually, with beating between additions, keeps the butter and sugar mixture emulsified. If eggs go in too fast, the batter can curdle or separate, which can make the finished cake coarse and heavy.
“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.
