Why it works: Butter and flour are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Sultana 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. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare
Preheat the oven to 350°F (175°C).
Make the batter
Cream the butter and sugar together until light and fluffy.
Add the eggs one at a time, mixing well after each addition.
Sift together the flour and baking powder, then fold into the mixture.
Gently fold in the sultanas and ground rice.
Pour the batter into greased cake pans.
Bake
Bake for about 30-40 minutes or until a toothpick comes out clean.

Butter and flour 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
- Eggs
- Bind the batter and add structure and richness as they set in the oven.
- Flour
- Provides the main structure that sets as the cake bakes.
- Baking powder
- Releases gas in the batter, helping the cake rise.
- Butter
- Adds fat for a tender crumb and rich flavor.
- Castor sugar
- Sweetens the cake and helps trap air when creamed with butter.
- Sultanas
- Add chewy texture and sweetness throughout the cake.
The step that matters
Creaming the butter and sugar. Beating butter and sugar together traps air bubbles that help give the cake a light texture. Under-creaming leaves a dense cake, while over-mixing after the flour is added can toughen it.
“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.
