Why it works: Sugar and vanilla are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 35,032 recipes. Both carry beta-damascenone, which smells apple, rose. The science ↓

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
Preheat your oven to 350°F (175°C).
Make the batter
Beat the butter until creamy.
Gradually add the sugar and flour, mixing well.
Beat in each egg separately.
Continue adding flour and eggs until well mixed.
Stir in the sultanas, lemon rind, salt, candied peel, currants, and vanilla essence.
Bake
Pour the batter into a cake tin lined with paper.
Bake for about 2 hours.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- All-purpose flour
- Provides the starch and gluten that form the cake's structure as it bakes.
- Unsalted butter
- Creamed with sugar to trap air, giving the cake a tender, rich crumb.
- Castor sugar
- Sweetens the cake and, creamed with butter, helps aerate the batter.
- Eggs
- Bind the batter and add structure, richness and moisture to the crumb.
- Sultanas
- Add moisture and sweetness, and are the main fruit in the cake.
The step that matters
Beat in each egg separately. Adding eggs one at a time lets each one fully emulsify into the butter and sugar. Adding them all at once can cause the batter to curdle, which weakens the crumb.
Swap the currant
How well each one fits the dish's main ingredients (flour, butter, sugar, egg, lemon, vanilla):
- Blueberryfits better
- Blackberryfits better
- Raisinfits better
- Currantthe original
Fit is the average pairing score against flour, butter, sugar, egg, lemon, vanilla. Candidates are from the same food group and used in at least 100 recipes.
