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 egg yolks and mix well.
In a separate bowl, beat the egg whites until stiff peaks form.
Combine the milk, flour, baking soda, and cream of tartar in the butter mixture, mixing until smooth.
Divide the batter into three equal parts.
Bake the layers
Bake two parts as plain cake in three long, shallow pans.
To the remaining batter, fold in the floured raisins, currants, citron, molasses, brandy, and spices.
Bake the fruit cake and let it cool.
Assemble and finish
Layer the fruit cake between the two plain cakes with jelly in between.
Press lightly to adhere, trim the edges, and frost as desired.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

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, giving the cake a tender, rich crumb.
- Eggs
- Yolks enrich and bind the batter; whites, beaten to stiff peaks, add lift and structure.
- All-purpose flour
- Forms the main structure of the cake as the batter sets in the oven.
- Baking soda
- Reacts with the acid in the batter to produce gas that helps the cake rise.
- Cream of tartar
- Acidifies the batter, helping the leavening react and stabilizing the structure.
- Raisins
- Add chewy texture and concentrated sweetness to the fruit layer.
The step that matters
Fold the fruit into the batter gently. Heavy fruit pieces can sink or the batter can deflate if it is overmixed, so the cake may bake unevenly and lose its lift.
Swap the currant
How well each one fits the dish's main ingredients (butter, sugar, egg, milk, flour, cream, raisin):

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