Why it works: Flour and almond are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 8,673 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Prune Almond 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 cake
Preheat the oven to 350°F (175°C).
Cream the butter and sugar together until light and fluffy.
Add the milk, corn starch, flour, and baking powder; mix well.
Fold in the egg whites gently until combined.
Pour the batter into a greased dripping pan and bake until golden.
Fill and frost
Once baked, cut the cake in half crosswise.
Prepare enough boiled frosting for two layers.
Mix ⅓ of the frosting with the chopped prunes and almonds.
Spread the prune‑almond mixture between the layers and on top.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creams with sugar to trap air, giving the cake a light, tender crumb.
- Egg whites
- Folded in to add lift and structure as the batter sets in the oven.
- Baking powder
- Releases gas during baking so the cake rises and becomes airy.
- Flour
- Provides the main structure that holds the cake together as it bakes.
- Corn starch
- Softens the crumb, giving a finer, more tender texture than flour alone.
- Prunes
- Add moisture and a rich, sweet flavour to the filling.
The step that matters
Folding in the egg whites. Folding gently keeps the air beaten into the whites intact. Stirring vigorously knocks out that air, so the cake rises less and turns denser.
“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.
