Why it works: Raisin and flour 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 ↓
Eggless White Fruit 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
Preheat the oven to 350°F (175°C).
In a bowl, rub the fruit and nuts together with 1 tablespoon of flour.
Sift 1 teaspoon of baking powder with 2 cups of flour.
Mix and bake
Dissolve the baking soda in 1 tablespoon of hot water and mix it into the batter.
Combine all ingredients and mix well.
Pour the batter into a greased cake pan and bake until a toothpick comes out clean.

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
- Adds fat and richness, contributing to a tender crumb and flavor.
- Baking soda
- Reacts with the acidic fruit and sugar to help the cake rise and brown.
- Baking powder
- Releases gas during baking, helping the cake rise and become light.
- Flour
- Provides the structure that holds the cake together as it bakes.
- Sugar
- Sweetens the cake and helps it brown and keep moisture.
- Pineapple
- Adds moisture and fruity acidity to the batter.
The step that matters
Dissolving the baking soda in hot water before mixing. Baking soda must be fully dissolved and evenly distributed through the batter, or pockets of it can leave soapy, bitter spots and uneven rising. It needs to be mixed in promptly so it reacts while the batter is still airy.

Fit is the average pairing score against sugar, butter, raisin, almond, flour. Candidates are from the same food group and used in at least 100 recipes.
