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 ↓

Ingredients
Directions
The book says “a brisk oven”. The 350°F in the steps is the modern equivalent, not the book's own figure.
Make the batter
Beat the butter until creamy.
Add the sugar and flour, mixing well.
Stir in the sultanas and chopped almonds.
Add the mixed peel and spice.
Incorporate the beaten yolks and whites of the eggs.
Stir thoroughly and pour in the brandy.
Bake
Pour the mixture into a prepared cake tin.
Bake in a moderate oven (350°F / 175°C) for 3.5 hours.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Bind the batter and add structure and richness as the cake bakes and sets.
- Butter
- Adds fat and richness, and creaming it traps air that gives a tender crumb.
- Flour
- Provides the structure that holds the cake together as the eggs and butter set.
- White sugar
- Sweetens the cake and helps give it a tender texture and browned crust.
- Sultanas
- Add moisture and chewy sweetness throughout the cake.
- Brandy
- Adds liquid and aroma, flavouring the cake as it is stirred through the batter.
The step that matters
Bake low and long. A rich fruit cake with this much butter and egg needs a moderate oven for a long time so the centre sets fully before the outside over-browns. Baking too hot risks a dark crust and a raw middle.
