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.
