Why it works: Pistachio and nuts match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 425 recipes. Both carry alpha-pinene, which smells pine, turpentine. The science ↓
Genoese 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
Beat the butter until creamy.
Gradually add the sugar, flour, sultanas, chopped mixed peel, and well-beaten eggs. Mix well for a few minutes.
Add the blanched and chopped almonds and pistachio nuts, followed by the lemon rind and baking powder.
Bake and finish
Line a buttered tin with buttered paper, extending it 2-3 inches above the tin.
Pour in the mixture and bake at 350°F (175°C) for 1.5 hours.
Once the cake is completely cool, cover it with coffee icing.

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
- Bind the batter and add structure and lift as the cake bakes.
- Flour
- Provides the structure that holds the cake together as it sets.
- Castor sugar
- Sweetens the cake and helps trap air when creamed with butter.
- Baking powder
- Releases gas in the oven so the cake rises and becomes lighter.
- Sultanas
- Add chewy sweetness and moisture throughout the cake.
The step that matters
Beating the butter until creamy. Creaming softened butter with sugar traps air bubbles that expand in the oven and give the cake its lift. Under-creamed butter leads to a dense cake.
