A sop is a piece of bread or toast that is soaked in liquid food and then eaten. In medieval cuisine, sops were very common. Sops were served with wine, soup or broth, and then picked apart into smaller pieces to soak in the liquid. At elaborate feasts, bread was often pre-cut into finger-sized pieces rather than broken off by the diners themselves. French onion soup, originating in its current form in the 18th century, can be considered a modern-day sop. - Source: Wikipedia
