I had some obvious issues with this bake. A lot of butter was lost during the bake, I didn't take pictures of the tray but probably half a stick.

My recipe was:

500g bread flour 300g water 80g sugar 300g butter

Made the dough, let it proof for 2 hours then added butter and laminated with 3 folds 3 times (or maybe 4 I forget) chilling for an hour in between. Baked for 25 mins at 400f which was a bit hotter and longer than the recipe I was trying to follow.

I probably could have given it more fridge time for a cold proof before baking, I only had them in the fridge for an hour and a bit before going into the oven after shaping. My first concern is the raw dough, I wasn't expecting to get good lamination on my first try but I would have expected it to be fully cooked. The tops were getting pretty dark which is why I pulled them out.

Any advice or criticism is appreciated!
