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 ↓
Light Fruit Cake
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 350°F (175°C).
Cream together the butter and sugar until light and fluffy.
Add the eggs one at a time, mixing well after each addition.
Stir in the sweet milk.
In a separate bowl, combine the flour, cream of tartar, and baking soda.
Make the batter
Gradually add the dry ingredients to the wet mixture, mixing until just combined.
Fold in the seedless raisins.
Pour the batter into a greased cake pan.
Bake
Bake for about 50 minutes or until a toothpick inserted in the center comes out clean.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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
- Flour
- Forms the main structure of the cake as its proteins set during baking.
- Eggs
- Bind the batter and add structure and richness as they set.
- Butter
- Adds fat for tenderness and flavor, and helps trap air when creamed with sugar.
- Sugar
- Sweetens the cake and helps create a light, fluffy texture when creamed.
- Cream of tartar
- Acidifies the batter and works with baking soda to help the cake rise.
- Baking soda
- Reacts with the acidic ingredients to produce gas that leavens the cake.
The step that matters
Gradually add the dry ingredients to the wet mixture. Mixing only until just combined keeps gluten development low, so the cake stays tender rather than tough. Overmixing after the flour goes in develops gluten and toughens the crumb.
Swap the raisin
How well each one fits the dish's main ingredients (butter, sugar, flour, milk, egg, cream):
- Vanillafits better
- Raisinthe original
- Coconutfits less well
- Figfits less well
Fit is the average pairing score against butter, sugar, flour, milk, egg, cream. Candidates are from the same food group and used in at least 100 recipes.
