Sorrel-Wrapped Sardines in White Wine

To clean the sardines, hold each under water and rub gently with fingertips against the grain of the scales to remove them, split open the abdomen with forefinger, empty it, and pinch off the head. Gently pull back the filets, forcing with fingertips to loosen them from the spinal column, starting at the head end, and break off the bone close to the tail, leaving the filets attached to the tail. Rinse and sponge dry between paper towels.
