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
Mix the batter
In a large bowl, combine sour milk, baking soda, molasses, and corn syrup.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sour milk
- Its acidity reacts with baking soda to produce gas that lifts the bread.
- Baking soda
- Reacts with the acidic sour milk to release carbon dioxide, leavening the batter.
- Molasses
- Adds moisture, dark colour, and a deep sweet flavour.
- Yellow cornmeal
- Adds coarse texture and body to the batter.
- Graham flour
- Contributes a nutty flavour and a hearty, coarse crumb.
- Rye flour
- Adds a tangy flavour and a dense, moist crumb.
The step that matters
Steam the cans for 2 hours. Steaming keeps the batter moist and cooks it gently without drying the crust. Sealed cans must stay covered so steam cooks the bread evenly, and the baking soda reaction needs the batter mixed promptly so the rise is not lost.
Swap the raisin
How well each one fits the dish's main ingredients (milk, molasses, corn, syrup, flour, rye):
- Raisinthe original
- Vanillafits about as well
- Figfits less well
- Cherryfits less well
Fit is the average pairing score against milk, molasses, corn, syrup, flour, rye. Candidates are from the same food group and used in at least 100 recipes.
