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
Make the batter
Cream the butter and sugar together until light and fluffy.
Add the well-beaten egg yolks.
Alternately mix in the sifted flour with cream of tartar and baking soda.
Add the milk.
Fold in the well-beaten egg whites gently.
Prepare and bake
Prepare three greased oblong shallow tins of equal size.
Divide the batter into three equal parts.
Bake two parts as plain cake.
Dredge the fruit with a little flour before mixing.
Add the chopped raisins and citron to the third part of the batter.
Bake all layers until done.
Assemble and finish
Layer the fruit cake between the two plain cakes, using jelly or white icing as filling.
Press the layers lightly together.
Trim the edges evenly.
Cover with white icing.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Forms the structure that holds the cake's crumb together as it bakes.
- Butter
- Creaming with sugar traps air and gives the cake a tender, rich texture.
- Eggs
- Yolks add richness and emulsify the batter, while whites add lift and structure.
- Sugar
- Sweetens the cake and helps creaming trap air for a light crumb.
- Baking soda
- Reacts with the acidic cream of tartar to produce gas that makes the cake rise.
- Citron
- Adds candied fruit flavour and chewy texture to the fruit layer.
The step that matters
Fold in the well-beaten egg whites gently. Beaten whites hold air bubbles that help the cake rise. Vigorous stirring deflates them, leaving a denser layer that rises less evenly.
Swap the mace
How well each one fits the dish's main ingredients (milk, butter, cinnamon, egg, brandy, flour, raisin):
- Nutmegfits better
- Cardamomfits better
- Clovefits better
- Macethe original
Fit is the average pairing score against milk, butter, cinnamon, egg, brandy, flour, raisin. Candidates are from the same food group and used in at least 100 recipes.
