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 ↓

Oven, in the book's wordsA moderate oven

Ingredients

Directions

The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.

Prepare

  1. Preheat the oven to 350°F (175°C).

Mix and bake

  1. In a large bowl, combine the bran, flour, sour milk, brown sugar, chopped raisins, baking soda, and salt. Mix until well combined.

  2. Pour the batter into two small loaf pans.

  3. Bake for 1 hour or until a toothpick inserted in the center comes out clean.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Flour and milk barely smell alike, yet cooks put them together in 78,219 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

Bran
Adds fibre and a hearty, dense texture to the crumb.
Flour
Provides the structure that holds the loaf together.
Sour milk
Adds moisture and acidity that reacts with the baking soda to lift the loaf.
Brown sugar
Adds sweetness, moisture and a caramel note to the crumb.
Baking soda
Reacts with the acidic sour milk to produce gas that makes the bread rise.

The step that matters

Checking for doneness. Baking soda starts reacting as soon as it meets the sour milk, so the batter should go into the pans and the oven without delay. A dense bran batter can look set on top while the centre is still wet, so test the centre with a toothpick rather than relying on colour or the timer alone.

Swap the raisin

How well each one fits the dish's main ingredients (flour, milk, sugar):

  1. Vanillafits about as well
  2. Raisinthe original
  3. Figfits less well
  4. Blueberryfits less well

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