When preparing puff pastry, a thick layer of butter is folded inside a sheet of dough. It is then rolled thin, folded over, and rolled again; the last two steps are repeated several times to create thin layers. What is this process called?

Answer Lamination

Laminating pastry dough creates multiple layers of tender, flaky pastry as the butter between the layers heats and creates steam which then puffs the crust. The heat of the oven dries and crisps the layers.
