Knead the dough for a few minutes until it's nice and smooth. Don't dump flour on top of the dough while kneading, rather keep your hands floured as well as the surface under the dough. This will keep you from folding too much flour inside the dough. The butter might ooze out, but just keep kneading. If it starts sticking to the surface, use a
scraper to scrape the dough up and add it back to the ball of dough.
