David mentions a sticky dough, mine was manageable at all times, in fact I had to add a bit more water but that's usually the case at high altitudes. I used a 9" cast iron skillet, on second thought, maybe not a good choice. It was non stick and the kouign amann came out beautifully, but I feel it got a little too caramelised at the bottom. The cast iron is great at retaining heat so maybe that's why mine browned quite a bit on the bottom but not enough on top. Of course, the best bits were the over caramelised bottom bits. I used a European Style butter: my local grocery store had Challenge European Style. My only concern is that, even though there were layers in the end product, some of them were a little dry. I think maybe a butter paste might work better (I made my croissants with a paste and they were beautifully moist and flaky) or could try smaller chunks to get better butter distribution. Other than that, the bread was very decadent and delicious; buttery and sweet with the perfect salty balance.
