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 ↓
Genoa 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
Cream the sugar and butter together for about 20 minutes.
Add the cleaned sultanas, candied peel cut into shreds, and the eggs one by one.
Add the peeled and chopped almonds, baking powder, and grated lemon rind.
Bake
Bake in a well-buttered and paper-lined tin for about 1 hour at 350°F (175°C).
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creamed with sugar to trap air, giving the cake a light, tender crumb.
- Eggs
- Add structure and richness as they set in the oven, binding the cake together.
- Flour
- Forms the main structure of the cake once baked.
- Baking powder
- Releases gas in the oven, helping the cake rise.
- Sultanas
- Add moisture and sweetness through the crumb.
- Almonds
- Add texture and a nutty flavour to the cake.
The step that matters
Creaming the sugar and butter. Beating for the full time incorporates air into the fat, which gives the cake lift and a fine crumb. Under-creaming leaves a dense result, while the eggs added afterwards must be incorporated gradually so the batter does not split.
