A sop is a piece of bread or toast that is drenched in liquid and then eaten. In medieval cuisine, sops were very common; they were served with broth, soup, or wine 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. The bread or croutons traditionally served with French onion soup, which took its current form in the 18th century, can be considered modern-day sops.
