Why it works: Sweet potato and flour work together. They rank in the top 9% of all ingredient pairs, and cooks put them together in 627 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Sweet Potato Rolls
Ingredients
Directions
Make the dough
Dissolve yeast in warm water.
Add salt and shortening, eggs and sweet potatoes.
Add flour to mixture, 1 cup at a time, beating after each addition thoroughly. The last cup may need to be mixed by hand.
Knead on bread board about 5 minutes until elastic.
Cover and refrigerate 2 hours or more.
Shape and bake
Divide dough in half.
Roll to 1/4 inch thickness.
Spread with butter.
Cut in 16 wedges and roll each from large end.
Place on oiled sheet (pan) point down.
Let rise 1 hour.
Repeat the same process with the other half of the dough.
Bake 15-20 minutes at 350 degrees.
Brush with butter.
Nutrition, whole recipe (rough)
Counts 5 of 6 ingredients. The other 1 aren't in our nutrition table and add nothing above, so the real totals are higher.
What these numbers assume: 5 portions
| Ingredient | Portion assumed | kcal |
|---|---|---|
| Flour | 1 cup (125g) all-purpose | 455 |
| Potato | 1 medium (173g) baked | 161 |
| Butter | 1 tbsp (14g) | 102 |
| Egg | 1 large egg (50g) | 78 |
| Salt | 1 tsp (6g) | 0 |
| Water | not in our table | 0 |

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
- Yeast
- Ferments the dough so it rises and becomes light.
- Flour
- Forms the gluten structure that gives the rolls their chewy crumb.
- Eggs
- Add richness and help bind the dough.
- Sweet potatoes
- Add moisture and softness to the dough.
- Shortening
- Tenderizes the dough and adds fat for a soft texture.
The step that matters
Adding the flour. Flour must be incorporated thoroughly, one cup at a time, so the gluten develops evenly. Unmixed pockets of flour or uneven gluten can make the dough dense and uneven in texture.
Swap the sweet potato
How well each one fits the dish's main ingredients (egg, flour, butter):
- Chivefits better
- Shallotfits better
- Leekfits better
- Sweet potatothe original
Fit is the average pairing score against egg, flour, butter. Candidates are from the same food group and used in at least 100 recipes.
