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 ↓
Dried-apple or Economical Fruit-cake
Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the fruit and spice mixture
Soak the apples in water overnight.
Drain and chop the soaked apples.
In a saucepan, combine the chopped apples, molasses, and spices; bring to a boil, then simmer gently for 20 minutes, stirring occasionally.
Let the molasses mixture cool.
Make the batter
Cream the butter and sugar together.
Stir in the butter, sugar, egg, flour, and baking powder; beat for 3 to 4 minutes.
Dissolve the baking soda in a few drops of boiling water.
Coat the raisins in flour and set aside.
Beat in the dissolved baking soda for a minute, then gently stir in the raisins.
Bake
Prepare two large loaf pans lined with greased parchment paper.
Fill each pan halfway with batter.
Bake in a preheated oven at 400°F (200°C) for 15 minutes.
Reduce the heat, cover with brown paper, and bake for an additional 30 minutes or until a skewer comes out clean.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Dried sour apples
- Provide fruit pieces and tartness that flavour the cake through its dense crumb.
- Molasses
- Adds dark color, moisture, and deep sweetness while helping the crumb stay tender.
- Butter
- Adds fat for richness and a tender texture.
- Flour
- Forms the structure that holds the cake together as it bakes.
- Baking soda
- Reacts with the molasses acidity to lift the batter and aid rising.
- Egg
- Binds the batter and adds structure and richness.
The step that matters
Dissolving and folding in the baking soda. Baking soda must be dissolved fully and mixed in briefly so it reacts evenly with the acidic molasses; overbeating or uneven distribution can cause dense patches or a collapsed rise.
