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

Oven, in the book's wordsA moderate oven

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

  1. Beat the butter until creamy.

  2. Gradually add the sugar, flour, sultanas, chopped mixed peel, and well-beaten eggs. Mix well for a few minutes.

  3. Add the blanched and chopped almonds and pistachio nuts, followed by the lemon rind and baking powder.

Bake and finish

  1. Line a buttered tin with buttered paper, extending it 2-3 inches above the tin.

  2. Pour in the mixture and bake at 350°F (175°C) for 1.5 hours.

  3. Once the cake is completely cool, cover it with coffee icing.

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

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.
