Julia made the puff pastry on her show. What I remember most was that each time she folded it, she would gently make an indentation with her fingers to show herself what fold she was one. All the way up to eight times she folded it. And she added more than a pound of butter to it. She would add butter to each fold.
It looks like a lot of work yet at the same time the hardest part is to keep it cold with the butter. The folding part is easy, if you can remember how many times you have folded it.
