SWEET POTATO BRAIDED BREAD LOAF[OVERNIGHT DOUGH METHOD]

This is actually a Nastar bun recipe with cheddar cheese filling but I used it to bake the braided loaf as I was short of time.  It turns out well, the texture is soft and moist. 
You can make 10 Nastar buns from this quantity. Just divide dough into 10 portions.  Roll each portion into a rectangle, fill with a piece of cheddar cheese.  Then roll up into a swiss roll, seal the edges, cut across the buns.  Place bun in a paper cup to proof until double in size.  Before baking, brush with egg glaze and top up with small bits of cheese.  Baked at 180 degrees C for 20 minutes.  I will try to bake these buns when I have enough time to spare.
The quantity in bracket [in red ink] is for 1 loaf of bread.
