Why it works: Molasses and sugar are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 9,225 recipes. Both carry ethanol, which smells alcoholic, ethereal. The science ↓

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.
Make the sponge
Dissolve the yeast cake in the warm water.
Add the dissolved yeast to the potato water along with the salt.
Stir in 2 cups of flour and set the mixture to rise in a warm place.
Once light, mix in the molasses, sugar, and melted fat into the sponge.
Knead and rise
Add the remaining flour and bran.
Knead the dough thoroughly on a floured surface until it is soft but not too sticky.
Let the dough rise in a warm place until it doubles in size.
Shape and bake
Shape the dough into loaves and let them rise again until doubled.
Bake in a moderate oven at 350°F (175°C) for one hour.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- White flour
- Provides the gluten network that traps gas and gives the loaves their structure.
- Yeast
- Ferments the sugars and produces the gas that makes the dough rise.
- Bran
- Adds fiber and a coarser texture, and can weaken gluten so the loaf is denser.
- Molasses
- Feeds the yeast and adds sweetness, color, and a deeper flavor.
- Potato water
- Supplies moisture and nutrients that help the yeast become active.
The step that matters
Knead until soft but not too sticky. Kneading develops gluten so the dough can hold gas. Too much added flour makes the loaf dry and dense, while a very sticky dough is hard to shape and may not hold its rise.
Swap the potato
How well each one fits the dish's main ingredients (molasses, flour, sugar):
- Arrowrootfits better
- Sweet potatofits better
- Beetrootfits better
- Potatothe original
Fit is the average pairing score against molasses, flour, sugar. Candidates are from the same food group and used in at least 100 recipes.
