I had a batch of dough that have been siting in the fridge since last Thursday. I had added 50 g of flour to my regular recipe of 500 g. I didn't add any additional flour while kneading where with my regular recipe I add about 12 g while kneading, the dough gets sticky.
I had only couple hours of resting after balling... I placed the balls in my home oven with the light on to get them to rise faster.
I didn't have time to take pictures, hungry people were waiting. I took left over to work. See attached picture after microwaved.
I never had this beautiful dark brown crust before, it tasted great. I am not sure if the dark crust was contributed to additional flour in my recipe or to something else.
