    Squeeze the butter cubes between your fingers to flatten them down. If they are too solid,
    wait a little bit and try again...

+   Drizzle the :amnt:`150 g` of water over the mixture and gently incorporate with your fingers, do not knead.
    Once incorporated, invert the bowl onto the working surface. It should be very shaggy and dry, with lots of dry flour hanging around.
    Gather the "dough" into a rough square and start rolling. The goal is to flatten the butter even more into very thin sheets.
    Use the bench scraper to fold the "dough" onto itself (it is still expected for it to not fully hold together here)
