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 ↓
Oatmeal Bread
Ingredients
Directions
The book says “a very slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the dough
Stir the oatmeal while pouring in the boiling water.
Add molasses and brown sugar while stirring, then set aside to cool.
Dissolve the yeast cake in lukewarm water and add it to the oatmeal mixture when it is lukewarm.
Add enough flour to thicken the dough to the consistency of white bread.
Bake
Bake in a slow oven at 300°F (150°C).
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

Butter and flour 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
- Raw oatmeal
- Adds hearty body and a nutty, chewy texture to the crumb.
- Molasses
- Adds sweetness, dark colour and moisture to the loaf.
- Brown sugar
- Feeds the yeast and adds sweetness and moisture to the loaf.
- Yeast cake
- Ferments the dough, producing gas that makes the bread rise.
- Flour
- Provides gluten structure that traps gas and sets the loaf's shape.
The step that matters
Add the yeast when the mixture is lukewarm. Yeast is killed by high heat, so the oatmeal mixture must cool to lukewarm before adding it. Too hot and the dough will not rise.
Swap the walnut
How well each one fits the dish's main ingredients (molasses, sugar, butter, flour):
- Almondfits better
- Chestnutfits better
- Hazelnutfits about as well
- Walnutthe original
Fit is the average pairing score against molasses, sugar, butter, flour. Candidates are from the same food group and used in at least 100 recipes.
