Once I'd let them rest for 30 minutes (more on resting times shortly!), I went to roll out all five doughs. The wettest dough and the driest dough were completely unworkable. They simply wouldn't pass through the roller—one was incredibly sticky; the other crumbled into dry clumps. Sometimes, a longer resting time can help a dough hydrate more, and it is possible that the driest of these could be rehabilitated with additional time. We'll get to the pros and cons of long rests in a bit.
