Purple yam bun (紫薯玫瑰馒头)

I mail ordered a case of 19 lb purple yam from Hawaii Veggie Farm. So I am into experimenting purple yam recipes. One of the prettiest thing I found online is the purple yam bun that look like rose buds.

Ingredients:

Purple yam - 200g
All purpose flour - 250g
Warm water (or milk) - 15g at 90-110°F
Yeast - 2.5g
Sugar - 5g

Steps:

1. Peel and steam purple yam. Mash it and let it cool.

2. Dissolve yeast and sugar fully in warm water. Add in flour, and purple yam puree. Add water if needed. Knead until dough is smooth.

3. Cover the dough and set aside for 2 hours, or until the dough has expand to 1.5 times the original volume.
4. Knead the dough and portion into smaller dough. Each small dough will make two buns.

5. For each small dough, roll it and split into 6 parts, while one of them is smaller.

6. Roll the smaller dough into a football shape; and the other 5 dough to dumpling skin shape (round shape; thicker in the center)

7. Overlap the 5 round skins like the picture below. Use a chopstick to indent a center line.

8. Place the football shape dough on the top skin, and use it as the core to roll up all skins.

9. Split the roll in the middle, and you will get two roses.

10. Let the roses sit for 10 minutes,

11. Place in steamer to steam 10 minutes.
