Why it works: Flour and raisin 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 ↓
Ribbon 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.
Prepare the batter
Preheat the oven to 350°F (175°C).
Cream the butter and sugar together until light and fluffy.
Add the milk and egg yolks, mixing well.
In a separate bowl, combine the flour, baking soda, and cream of tartar.
Gradually add the dry ingredients to the wet mixture, mixing until smooth.
Divide the batter into three parts.
Bake the layers
Bake two parts as plain cake layers.
To the third part, fold in the raisins, currants, citron, molasses, wine or brandy, and spices.
Bake the spiced batter as a separate layer.
Assemble and frost
Once cooled, layer the spiced cake between the plain cake layers with jelly.
Press lightly to assemble and frost the cake.

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, giving the cake a tender, rich crumb.
- Eggs
- Yolks enrich and bind the batter; whites beaten separately add lightness and structure.
- Pastry flour
- Forms the cake's structure once its starch sets during baking.
- Baking soda
- Reacts with the acid in the batter to produce gas that helps the cake rise.
- Cream of tartar
- Adds acidity that works with the baking soda to leaven the batter and stabilise it.
- Raisins
- Add moisture and sweetness to the spiced layer as they plump in the batter.
The step that matters
Folding in the fruit and spices. Heavy fruit can sink to the bottom of the batter if overmixed or left to sit, leaving an uneven spiced layer. Gentle folding keeps the fruit evenly distributed while the batter keeps its air.
Swap the currant
How well each one fits the dish's main ingredients (butter, sugar, milk, egg, flour, cream, raisin):

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