Place the smooth dough on a lightly floured work surface and roll it directly into a long, even log (uniform thickness makes it easier to portion later).
Pinch the log into evenly sized portions (about 20g each—consistent size ensures uniform roses). Roll each portion into a smooth small ball and cover with a damp cloth to prevent drying out.
Take one small ball and roll it into a dumpling wrapper-sized round (thin at the edges, thick in the center, about 5-6cm in diameter—perfect for rolling into roses later).
Repeat to make more wrappers, grouping them into sets of 6 (6 wrappers create a rose with full, layered petals).
Arrange the 6 wrappers in a row for each set, overlapping each adjacent wrapper by about 1/3. Use a chopstick to gently press a line down the center of the arranged wrappers (this makes cutting easier and keeps the rose shape stable).
Start rolling tightly from one end to the other to form a complete log. Roll the log gently on the work surface once to refine its shape.
Use a knife to cut the log in half along the pressed line—each half is the base of a rose (place the cut side down as the flower base for stability).
Gently shape the rose petals by flipping the edges outward to mimic a blooming rose. Pinch the base lightly to secure it (prevents unraveling during steaming). One beautiful pumpkin rose bun blank is done! Repeat to make all blanks, arrange them neatly on the work surface, cover with a damp cloth, and let rest for 10 minutes (a short rest helps them puff up better during steaming—no fermentation needed).
