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 ↓
Boston Brown Bread
Ingredients
Directions
Mix the batter
Sift together the whole wheat flour, salt, and water-ground meal, and mix well.
Add the dark molasses and butter milk.
Add the half cup of milk in which the two level teaspoons of soda have been dissolved.
Add fruit and fill cans
For raisin bread, add the one-half box of seeded raisins that have been washed and pressed dry.
For fruit bread, add the one cup of mixed chopped fruits such as raisins, citron, cherries, or pineapple.
Fill the one pound baking powder cans two-thirds full and place them in a vessel of warm water.
Steam
Cover with several thicknesses of cloth and a top, and steam for three hours, adding more water if necessary.
Nutrition, whole recipe (rough)
Counts 7 of 8 ingredients. The other 1 aren't in our nutrition table and add nothing above, so the real totals are higher.
What these numbers assume: 7 portions
| Ingredient | Portion assumed | kcal |
|---|---|---|
| Flour | 1 cup (125g) all-purpose | 455 |
| Milk | 1 cup (244ml) whole | 149 |
| Butter | 1 tbsp (14g) | 102 |
| Grape | 1/2 cup (76g) | 62 |
| Molasses | 1 tbsp (20g) | 58 |
| Sugar | 1 tbsp (12.5g) granulated | 49 |
| Salt | 1 tsp (6g) | 0 |
| Fruits | not in our table | 0 |

The flavor team
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 butter barely smell alike, yet cooks put them together in 124,287 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
- Whole wheat flour
- Provides the main structure and the hearty, nutty body of the bread.
- Dark molasses
- Adds sweetness, moisture, and the dark colour and flavour characteristic of the loaf.
- Buttermilk (in the method)
- Its acidity reacts with the soda to lift the batter and keeps the crumb tender.
- Baking soda
- Reacts with the acidic buttermilk to produce gas that makes the bread rise.
- Raisins
- Add pockets of chewy sweetness and moisture throughout the bread.
The step that matters
Steam for three hours with enough water. The bread cooks by steam rather than dry heat, so the water bath must not run dry. Steady steam sets the crumb evenly; a dry pot can scorch the cans and leave the loaf underdone.
Swap the raisin
How well each one fits the dish's main ingredients (wheat, flour, molasses, butter, milk):
- Raisinthe original
- Vanillafits about as well
- Figfits less well
- Coconutfits less well
Fit is the average pairing score against wheat, flour, molasses, butter, milk. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
