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 gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Dissolve the baking soda in a little boiling water and add it to the molasses.
Mix all the ingredients together.
Rest and bake
Let the mixture stand for 1 hour.
Bake in a preheated oven at 350°F (175°C) for 1 hour and 15 minutes.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sour milk
- Acidity reacts with baking soda to produce carbon dioxide, helping the bread rise.
- Baking soda
- Reacts with the acidic sour milk to produce gas, leavening the batter without yeast.
- Molasses
- Adds moisture, dark color, and a rich sweetness with a slightly bitter edge.
- Egg
- Binds the batter and adds structure as it sets during baking.
- Graham flour
- Provides the main structure of the loaf through gluten and starch.
- Bran
- Adds fiber and a coarse, hearty texture, absorbing liquid in the batter.
The step that matters
Dissolving the baking soda before mixing. Baking soda must be fully dissolved and combined with the molasses so it reacts evenly through the batter. Undissolved pockets can cause uneven rising and bitter spots in the loaf.
Swap the raisin
The recipe marks raisin as optional. How well each one fits the dish's main ingredients (milk, molasses, sugar, egg, flour, nuts):
- Raisinthe original
- Vanillafits about as well
- Figfits less well
- Datesfits less well
Fit is the average pairing score against milk, molasses, sugar, egg, flour, nuts. Candidates are from the same food group and used in at least 100 recipes.
