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 ↓
Brown Sandwich Cake
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Make the batter
Preheat the oven to 350°F (175°C).
Cream the butter and brown sugar together until light and fluffy.
Add the eggs one at a time, mixing well after each addition.
Stir in the treacle and vanilla essence.
In a separate bowl, combine the flour, ground rice, mixed spice, ground ginger, and baking powder.
Gradually add the dry ingredients to the wet mixture, mixing until just combined.
Bake and finish
Pour the batter into sandwich tins and bake for 25-30 minutes or until a toothpick comes out clean.
Let the cakes cool, then spread icing between the layers and on top.
Decorate with walnuts.

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 they set during baking.
- Butter
- Adds fat and tenderness, and creaming it with sugar traps air that helps the cake rise.
- Brown sugar
- Adds sweetness and moisture, and its molasses gives the cake a deeper colour and flavour.
- Flour
- Forms the main structure of the cake as its proteins set during baking.
- Baking powder
- Releases gas in the batter so the cakes rise in the oven.
- Treacle
- Adds moisture, dark colour and a rich, slightly bitter sweetness.
The step that matters
Gradually add the dry ingredients to the wet mixture, mixing until just combined.. Overmixing once flour meets liquid develops gluten, which makes the cake tough and dense. Stopping as soon as the dry ingredients disappear keeps the crumb tender.
Swap the ginger
How well each one fits the dish's main ingredients (egg, butter, flour, rice, sugar, vanilla, walnut):
- Cinnamonfits better
- Nutmegfits better
- Turmericfits better
- Gingerthe original
Fit is the average pairing score against egg, butter, flour, rice, sugar, vanilla, walnut. Candidates are from the same food group and used in at least 100 recipes.
