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 ↓
Rich Christmas Cake
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
Preheat the oven to 300°F (150°C).
In a large bowl, beat the sugar, butter, and syrup until creamy.
Add the eggs one at a time, beating well after each addition.
In another bowl, mix the flour, mixed spice, candied peel, currants, sultanas, and almonds.
Combine the dry ingredients with the creamed mixture.
Dissolve the baking soda in a little milk and add it to the batter. Mix everything well.
Bake and finish
Pour into a greased and lined cake tin.
Bake for 2 to 3 hours until a skewer comes out clean.
Level the top of the cake.
Brush the top with egg white.
Apply almond icing.
Apply sugar icing.

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 sets.
- All-purpose flour
- Forms the gluten and starch framework that gives the cake its structure.
- Caster sugar
- Sweetens the cake and helps trap air when creamed with the fat.
- Baking soda
- Reacts with the acidic ingredients to help the cake rise.
- Lyle's golden syrup
- Adds moisture, sweetness and a soft, tender crumb.
The step that matters
Bake low and slow until a skewer comes out clean. A large, dense fruit cake can look set on top while the centre is still wet. Baking at a low temperature for the full time lets heat reach the middle without the outside burning, so test the centre with a skewer before removing it.
Swap the currant
How well each one fits the dish's main ingredients (flour, sugar, almond, egg, syrup):

Fit is the average pairing score against flour, sugar, almond, egg, syrup. Candidates are from the same food group and used in at least 100 recipes.
