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 ↓

Ingredients
Directions
The book says “a slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the batter
Preheat the oven to 300°F (150°C).
In a bowl, mix the graham flour, salt, and baking powder.
Add the raisins and molasses to the flour mixture.
Dissolve the baking soda in the buttermilk and add it to the mixture. Stir well until combined.
Bake
Pour the batter into pound baking powder cans.
Bake for one hour.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Graham flour
- Forms the body of the bread and gives it its hearty, wholesome texture.
- Molasses
- Adds sweetness, dark color, and moisture to the batter.
- Buttermilk
- Adds moisture and acidity that reacts with the baking soda to help the bread rise.
- Baking soda
- Reacts with the acidic buttermilk to produce gas that lightens the batter.
- Baking powder
- Provides additional leavening so the bread rises during baking.
- Raisins
- Add pockets of chewy sweetness throughout the bread.
The step that matters
Dissolve the baking soda in the buttermilk and stir well until combined. Baking soda must be fully dissolved and evenly mixed so it reacts with the acid in the buttermilk throughout the batter. Uneven mixing leaves dense pockets or bitter spots and uneven rise.
“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.
