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).
In a bowl, cream together the sugar and butter.
Add the eggs and sweet milk, and mix well.
Dissolve the baking soda in the milk and add it to the mixture.
Stir in the flour and salt, and flavor with lemon or almond extract.
Divide half the batter into two square pans.
Make the spiced batter and bake
To the remaining batter, add molasses, raisins, citron, cinnamon, cloves, and flour.
Pour this mixture into the other two pans.
Bake until a toothpick inserted in the center comes out clean.
Assemble
Layer the cakes with jelly or raspberry jam.

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
- Eggs
- Bind the batter and add structure as the cake sets in the oven.
- Butter
- Adds richness and tenderness through fat coating the flour.
- Flour
- Forms the cake's structure once heated and set.
- Baking soda
- Reacts with the acidity in the batter to help it rise.
- Sugar
- Sweetens the cake and helps keep it moist and tender.
- Molasses
- Adds moisture, dark colour and a deep sweet flavour to the spiced layers.
The step that matters
Baking until a toothpick comes out clean. Both batters are cooked in the same oven, so the cake can dry out if baked too long. Testing the centre with a toothpick shows when the crumb has set without overbaking.
