Why it works: Raisin and flour match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 9,075 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Christmas Fruit Cake
Ingredients
Directions
The book gives no oven temperature. The 300°F (150°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Preheat the oven to 300°F (150°C).
Make the batter
In a large bowl, whip the butter and sugar together until creamy.
Add the beaten eggs and mix well.
In a separate bowl, combine the fruits and spices with a little flour.
Gradually add the fruit mixture to the butter mixture, stirring to combine.
Bake and finish
Pour the batter into a prepared cake pan.
Bake for four hours. Ice if desired.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creams with sugar to trap air and give the cake a tender, rich crumb.
- Eggs
- Bind the batter and add structure and moisture as the cake sets.
- Flour
- Provides the structure that holds the heavy fruit suspended in the batter.
- Raisins
- Add moisture, chew and sweetness throughout the cake.
- Currants
- Add moisture, tartness and concentrated fruit flavour throughout the cake.
- Baking powder
- Releases gas in the batter to lift the cake as it bakes.
The step that matters
Gradually add the fruit mixture to the butter mixture. Adding the fruit in stages and stirring gently keeps the batter evenly mixed and prevents the heavy fruit from sinking to the bottom while the cake bakes.
