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 ↓
Raspberry Venice Cakes
Ingredients
Directions
Make the cake
Beat the eggs and sugar until very light.
Add the melted butter and stir in the flour lightly.
Spread the mixture in a square-edged tin about ¾ inch thick.
Bake until golden, then turn out to cool.
Assemble and finish
Split the cake with a sharp knife and spread raspberry jam in between.
Close the cake like a sandwich and spread the top with Royal Icing.
Cut into squares or lengths as desired.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whisked with sugar to trap air, giving the cake its light, risen structure.
- Sugar
- Whisked with the eggs for airiness and adds sweetness and tender browning.
- Butter
- Adds richness and moisture, giving a tender crumb after baking.
- Flour
- Provides the structure that holds the cake together once baked.
- Raspberry jam
- Adds fruity sweetness and moisture between the cake layers.
The step that matters
Stir in the flour lightly. Overmixing once flour is added develops gluten and makes the cake tough and dense. Folding gently keeps the air beaten into the eggs and sugar, so the sponge stays light.
