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
Prepare the batter
In a bowl, combine bread crumbs and sweet milk.
Stir in molasses, baking soda, salt, and the egg.
Add cornmeal and enough graham flour to achieve a thick batter.
Fold in the raisins.
Steam and serve
Pour the mixture into three one-pound baking powder cans.
Steam for 2½ to 3 hours.

Milk and flour 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
- Bread crumbs
- Provide bulk and a tender, moist crumb structure to the batter.
- Molasses
- Adds sweetness, dark colour and a rich, moist flavour.
- Baking soda
- Reacts with the molasses acidity to help the bread rise and lighten.
- Egg
- Binds the batter and helps set the structure as it cooks.
- Graham flour
- Thickens the batter and gives the bread its hearty, nutty texture.
- Raisins
- Add pockets of sweetness and chew throughout the bread.
The step that matters
Keep the batter thick before steaming. A batter that is too thin will turn dense and gummy, since the graham flour must absorb enough liquid to hold its structure. Adding flour until the batter is thick gives the bread a firm, sliceable crumb once steamed.
