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.
Make the batter
Cream the butter and gradually add the sugar.
Beat the egg yolks until very light and add to the mixture.
Add the flour and milk alternately, then fold in the stiffly beaten egg whites.
Divide and bake
Divide the batter into three parts.
In one part, add the raisins, currants, citron, molasses, brandy or coffee, and spices, flouring the fruit lightly.
Bake the two plain layers and the fruit layer in layer pans.
Assemble and finish
Place the fruit layer between the plain layers and spread white or pink icing or apple jelly between them.
Press the layers together lightly, trim the edges evenly, and frost with white icing.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creamed with sugar to trap air and give a tender, rich crumb.
- Eggs
- Yolks add richness and structure, while whites add lift and a light texture.
- Pastry flour
- Forms the structure of the cake when mixed with liquid and eggs.
- Baking powder
- Releases gas in the batter, causing the layers to rise.
- Sugar
- Sweetens the cake, tenderizes the crumb and helps the crust brown.
- Milk
- Adds moisture and hydrates the flour to build the batter's structure.
The step that matters
Folding in the stiffly beaten egg whites. The whites hold air bubbles that lift the layers. Folding gently keeps that air in, while stirring or beating hard collapses it and yields a denser cake.
Swap the currant
How well each one fits the dish's main ingredients (butter, sugar, egg, milk, flour, raisin, molasses):
- Vanillafits better
- Figfits better
- Datesfits about as well
- Currantthe original
Fit is the average pairing score against butter, sugar, egg, milk, flour, raisin, molasses. Candidates are from the same food group and used in at least 100 recipes.
