Why it works: Almond and flour 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 ↓
Cake, Plum
Ingredients
Directions
The book says “a slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Make the batter
Cream the butter in a bowl.
Add the sugar and treacle, and mix well.
Incorporate the eggs one at a time, beating well after each addition.
Mix in the warm milk until combined.
Gently fold in the currants, candied lemon peel, sweet almonds, and flour without overmixing.
Bake
Pour the batter into a greased cake tin.
Bake in a slow oven at 300°F (150°C) for at least 4 hours.

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 trap air and give a rich, tender crumb.
- Eggs
- Bind the batter and add structure and richness as they set in the oven.
- Flour
- Provides the main structure that holds the fruit and sets the cake's crumb.
- Moist sugar
- Adds sweetness and moisture, and helps the cake brown during the long bake.
- Currants
- Supply the fruit bulk and chewy texture throughout the cake.
The step that matters
Folding in the currants, peel, almonds and flour. Overmixing once flour is added develops gluten, which toughens the crumb. Folding gently keeps the batter light and stops the heavy fruit from sinking to the bottom.
Swap the currant
