Ingredients

For the Purple Sweet Potato Dough:

150 g steamed purple sweet potato
30 g sugar
120 ml warm water around 35°C
3 g yeast
300 g all-purpose flour

For the White Dough:

300 g all-purpose flour
30 g sugar
3 g yeast
150 ml warm water around 35°C

Instructions

Prepare the Purple Sweet Potato Dough:

Wash, peel, and cut about 500g purple sweet potatoes into small pieces.
Steam the pieces for about 25 minutes until soft.
Measure out 150g of the steamed purple sweet potato, then add 30g of sugar. Mash it with a fork until smooth (a potato masher can also be used). Let it cool slightly before using.
Combine the mashed purple sweet potato with 120ml warm water, 3g yeast, and 300g all-purpose flour. Mix with chopsticks until a shaggy dough forms, then knead until smooth.

Prepare the White Dough:

In a bowl, combine 300g all-purpose flour, 30g sugar, 3g yeast, and 150ml warm water. Mix with chopsticks until the dough forms, then knead until smooth.

Assemble the Mantou:

Roll out both the purple sweet potato dough and the white dough into rectangular shapes.
Place the white dough on top of the purple sweet potato dough.
Roll the dough from top to bottom into a cylinder shape.
Gently roll the dough into a long log. If the dough is sticky, sprinkle some flour on it.
Cut the log into evenly sized pieces.

Steam the Mantou:

Place the mantou pieces in a steamer, cover with the lid, and let them rise until doubled in size, about 45 minutes.
Steam over medium-high heat for 12 minutes, starting the timer when the water begins to boil.
After steaming, let the mantou sit for 5 minutes before opening the steamer to prevent them from collapsing.
