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 ↓
Raisin Bread
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 large bowl, mix the milk or cream, baking soda, molasses, and salt.
Gradually add the whole wheat flour, stirring until combined.
Fold in the chopped walnuts and halved raisins.
Bake
Pour the batter into a greased loaf pan, ensuring it is about 5 inches thick.
Bake for 1 hour or until a toothpick inserted in the center comes out clean.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Baking soda
- Reacts with the acidity in sour milk or molasses to produce gas that lifts the loaf.
- Whole wheat flour
- Provides the structure of the loaf as its proteins and starch set during baking.
- Molasses
- Adds sweetness, moisture, and a deep colour that contributes to browning.
- Milk or cream
- Supplies the liquid that hydrates the flour and dissolves the baking soda for even rising.
- Raisins
- Add pockets of moisture and sweetness throughout the crumb.
The step that matters
Testing for doneness. Whole wheat batter with molasses can look set on top while the centre is still wet. A toothpick inserted in the middle should come out clean, because undercooked centres collapse and turn gummy as they cool.
Swap the walnut
How well each one fits the dish's main ingredients (milk, molasses, wheat, flour, raisin):
- Almondfits better
- Chestnutfits about as well
- Walnutthe original
- Flaxseedfits about as well
Fit is the average pairing score against milk, molasses, wheat, flour, raisin. Candidates are from the same food group and used in at least 100 recipes.
