Why it works: Pistachio and almond match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 693 recipes. Both carry alpha-pinene, which smells pine, turpentine. The science ↓
Genoa Cake
Ingredients
Directions
The book says “a quick oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the batter
Cream the butter in a large bowl until smooth.
Add the sugar and cream together again until well combined.
Mix in the flour, candied peel, sultanas, and lemon rind.
Add the eggs one at a time, beating well after each addition.
Fold in the chopped almonds and pistachio kernels.
Finally, add the baking powder and mix until just combined.
Bake
Pour the batter into a shallow tin or sauté pan.
Bake in a moderate oven at 350°F (175°C) for 1.5 hours.

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 tender, rich crumb.
- Eggs
- Add structure and richness as they set in the oven, binding the fruit and nuts.
- Flour
- Forms the main structure of the cake once heated and set.
- Sugar
- Creams with butter for aeration and adds sweetness and browning.
- Sultanas
- Add moisture and chewy sweetness throughout the cake.
- Baking powder
- Releases gas in the heated batter, helping the cake rise.
The step that matters
Add the baking powder last and mix until just combined. Baking powder starts releasing gas as soon as it is wet and mixed. Overmixing after it is added knocks out that gas and toughens the crumb, so the cake rises less evenly.
