I made the mistake of not making the brioche dough the night before baking the buns, so I had to accomplish the task in a day. I started at 9 a.m. and finished at 9 p.m. And, I skipped one step in the lamination process, to save both time and butter.
My KitchenAid was up to the task of mixing the dough for 15 minutes. I did find I had to add a bit more flour, but hestitated adding too much for fear I would throw off the proportions of flour and butter. I was sorely tempted, however, but glad I didn't cave in, for my dough was easy enough to roll after the 4-hour refrigeration. The extra flour would not have been needed.
After the 30-minute cold rest, it was ready to roll for the sticky buns. I liked the method of painting the dough with the egg wash. Although I have made sweet rolls all my adult life, I had never used egg wash using a whole egg. My previous experiences were to either use butter, water or egg white. I used a ground pecan mixture for my nuts, a product I buy in bulk from a Mennonite store in Ohio. I was doubtful if there was enough cinnamon/sugar mixture, but after tasting the buns, I found it to be just right.
After rolling up the dough and slicing it (using the dental floss method by wrapping a length of floss around the dough, then criss-crossing the ends to get a perfect cut, I found I needed to make eight rolls, not seven. If I had cut seven rolls they would have been too tall, especially after the two-hour rise. I found two hours to actually be too much and wished I had let them rise a shorter time period. My rolls were, perhaps, overrisen as they were immense after coming out of the oven.
