Ingredient Notes (Milk vs Water vs Kefir)
| Liquid | Flavor Result |
|---|---|
| Milk | Soft, rich, classic |
| Water | More neutral, slightly lighter |
| Water kefir | Slight tang, deeper flavor |
Instructions
Step 1: Mix the Dough (Night Before)
In a large bowl or stand mixer, combine:
flour
milk (or water kefir or water)
mashed sweet potato
sourdough starter
Mix until combined and let rest for 30 minutes (autolyse).
Add:
honey or maple syrup
salt
softened butter
Knead until smooth and elastic (about 6–8 minutes).
Step 2: Bulk Fermentation
Cover and let rest at room temperature for 1 hour
Transfer to the refrigerator and ferment overnight
This slow fermentation builds flavor and improves texture.
Step 3: Shape the Rolls (Next Morning)
Remove dough from refrigerator
Let sit at room temperature for 45–60 minutes
Divide into 12 equal pieces (~85 g each).

Shape each piece into a tight ball.

Place into a buttered baking dish (slightly spaced apart).
Final Proof
Let the rolls rise until soft and puffy.
Time:
Room temp: 2–3 hours
Proof setting (optional): faster at ~75–80°F
What Properly Proofed Rolls Look Like
You’re looking for:
✔ noticeably puffed and expanded
✔ dough feels light and airy
✔ rolls are beginning to touch
✔ poke test: dent slowly springs back
If it springs back quickly → needs more time
If it stays indented → slightly overproofed
Bake
Preheat oven to 375°F
Bake for 18–22 minutes, until golden brown

Brush with melted butter immediately after baking.
Timing Example (Real-Life Schedule)
Night Before
7:00 pm – mix dough
7:30 pm – knead
8:30 pm – rest complete
9:00 pm – refrigerate
Morning
8:00 am – remove dough
9:00 am – shape rolls
9:30 am – begin final proof
11:30–12:00 pm – bake
Tips for Success
Use smooth, well-mashed sweet potato (no chunks)
Dough should feel soft but manageable—not overly sticky
Don’t skip the overnight rest—it improves both flavor and texture
Milk gives the most browning, while water kefir adds tang and fermentation benefits

Ingredient notes
Milk gives the most classic flavor, water keeps things simpler, and water kefir adds the most depth.
Honey and maple syrup both work well here; maple makes the sweetness slightly deeper and warmer.

Nutrition notes
Estimated with 2% milk, a 100% hydration sourdough starter, and no optional butter brush.
Using water or water kefir instead of milk lowers calories and saturated fat slightly.

Tips & tricks
- Use smooth, well-mashed sweet potato with no chunks for the softest dough.
- The dough should feel soft but manageable, not overly sticky.
- Do not skip the overnight refrigerator rest; it improves both flavor and texture.
- Milk gives the best browning, while water kefir adds more tang.
Storage & reheating
Store covered at room temperature for 1 to 2 days.
Refrigerate up to 5 days.
Freeze baked rolls up to 2 months; thaw and warm before serving.
Troubleshooting
If the rolls are dense, the dough likely needed more final proof time or the starter was not active enough.
If the dough feels very sticky, let it rest before adding extra flour so the sweet potato can fully hydrate the dough.
If the tops brown too fast, tent the pan loosely with foil for the last several minutes.
