750g batch 

750g flour
487g water (65%)
22g salt
7g yeast
30g butter
1 egg

Sesame and/or
Poppy seeds

NOTE:  Hand mixed method, but can also be mixed by machine.

Mix flour, water, yeast, egg and butter together. Let rest (autolyze) for 20 minutes.  Add salt and let rest another 20 minutes.  

Do a series of stretch and folds, 20 minutes apart.   (Usually 4 to 6 is enough).

Cover and leave dough to double.  

Divide dough into 12 pieces and shape each piece into a log.  Cover and let rest for 10 minutes.

Roll each log into a rope about 8" to 10" long.  Tie a loose knot in the middle and tuck one end down the middle and one end over and up the middle.  Place on parchment, cover and let rise until doubled. 

Preheat oven to 475°F

Spray with water, sprinkle with sesame or poppy seeds (or both) and bake for 20 to 25 minutes or until buns are golden brown.
