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 ↓
Fruit Sheet Cake
Ingredients
Directions
The book says “a moderately hot oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the batter
Preheat the oven to 350°F (175°C).
Cream the butter and sugar together until light and fluffy.
Add the eggs one at a time, mixing well after each addition.
Stir in the milk and almond extract.
Sift the baking powder with the flour and gradually mix it into the batter.
Add fruit and bake
Fold in the chopped fruit gently but thoroughly.
Pour the batter into a sheet pan and bake until golden brown.
Optionally, top with whole raisins or sprinkle with sugar before baking.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creaming with sugar traps air and gives the cake a tender, rich crumb.
- Eggs
- Add structure as they set and help bind the batter together.
- Flour
- Forms the main structure of the cake as its proteins set during baking.
- Milk
- Adds moisture and hydrates the flour so the batter can set evenly.
- Sugar
- Sweetens the cake and, creamed with butter, helps hold air for a light texture.
- Baking powder
- Releases gas in the batter so the cake rises and becomes light.
The step that matters
Folding in the fruit gently. Overmixing develops gluten in the flour and toughens the cake, while gentle folding keeps the batter airy and spreads the fruit evenly without crushing it.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
