Why it works: Milk and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Raised Sweet-potato Bread
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.
Prepare the batter
Boil, peel, and mash enough sweet potatoes to yield 1 quart of pulp.
Dissolve the yeast in the milk, then add the salt, sugar, and boiling water.
Mix in the mashed sweet potatoes and enough flour to make a thick batter.
Cover the batter with a thick towel and let it rise in a warm place until doubled in size.
Knead and shape
Once risen, mix in enough more flour to make a soft dough and knead for 5 minutes.
Divide the dough into three buttered iron pans, filling each half full.
Cover the pans and let the dough rise again until doubled in size.
Bake
Bake in a moderate oven at 350°F (175°C) until fully cooked.

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
- Sweet potatoes
- Add moisture, body and natural sweetness to the dough.
- Yeast
- Ferments the sugars, producing gas that makes the dough rise.
- Flour
- Provides gluten structure that traps gas and sets the crumb as it bakes.
- Milk
- Adds moisture and richness, softening the crumb and aiding browning.
- Sugar
- Feeds the yeast and adds sweetness and browning in the crust.
The step that matters
Letting the dough rise until doubled. Yeast needs enough time and warmth to build gas; underproofed dough bakes dense, while overproofed dough can collapse and lose structure.

- Potatofits about as well
- Leekfits about as well
Fit is the average pairing score against milk, sugar, flour, butter. Candidates are from the same food group and used in at least 100 recipes.
