Why it works: Potato and coffee work together. They rank in the top 12% of all ingredient pairs, and cooks put them together in 167 recipes. Both carry sotolon, which smells curry, maple. The science ↓
Rolls and Light Bread
Ingredients
Directions
Make the starter
Boil the potato until tender.
Dissolve half of the gem yeast-cake in lukewarm water.
Sift 1 pint of flour into a bowl.
Mash the hot potato smoothly.
Mix the mashed potato with the flour.
Add 1 teaspoon of sugar and ¼ teaspoon of salt.
Pour in the dissolved yeast.
Beat the batter well.
Cover the bowl.
Place the bowl in a warm spot.
Knead and shape
Sift the remaining 2 pints of flour onto a surface, reserving a little for kneading.
Mix in 1 tablespoon of lard, 1 teaspoon of sugar, and 1 teaspoon of salt.
Combine the batter with the flour.
Knead the dough well.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Provides the structure that holds the dough and rolls together as they rise.
- Potato
- Adds moisture and softness, helping the rolls stay tender.
- Yeast
- Produces gas that makes the dough rise and gives the rolls their airy texture.
- Lard
- Adds fat that tenderises the crumb and softens the texture.
The step that matters
Let the dough rise in a warm spot. Yeast needs warmth and time to produce gas; a cold or rushed rise leaves the rolls dense instead of light.
Swap the potato
How well each one fits the dish's main ingredients (flour, coffee, sugar):
- Arrowrootfits better
- Beetrootfits better
- Sweet potatofits better
- Potatothe original
Fit is the average pairing score against flour, coffee, sugar. Candidates are from the same food group and used in at least 100 recipes.
