Why it works: Orange and lemon match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 10,634 recipes. Both carry 3-hexenal, which smells apple, fruity. The science ↓

Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the batter
In a large bowl, cream the butter with a wooden spoon until smooth.
Gradually add the sugar, flour, salt, and eggs, mixing continuously.
Incorporate the remaining ingredients until well combined.
Bake
Pour the batter into a lined cake tin placed on a sturdy baking sheet.
Bake in a moderate oven at 350°F (175°C) for about 2.5 hours, without increasing the heat.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creams with the sugar to give the cake a tender, rich crumb and fat for flavour.
- Eggs
- Bind the batter and add structure and richness as they set in the oven.
- Flour
- Forms the main structure of the cake as its proteins set during baking.
- Sugar
- Sweetens the cake and helps keep it moist and tender while it bakes.
- Ground almonds
- Add moisture, richness and a nutty flavour that keeps the crumb tender.
- Brandy
- Adds aroma and flavour and helps the cake keep its moisture.
The step that matters
Bake without increasing the heat. A long, slow bake lets the large cake cook through evenly. Raising the heat sets and browns the outside before the centre is done, leading to a dense or cracked cake.
