Can you purge crawfish overnight?
Chef's answer
A 12-hour (or overnight) purge is sufficient for cleaning the exterior of crawfish and for the evacuation of most of the intestinal contents. A 12-hour duration will incur the least mortality and use less energy. Therefore, approximately 12 hours is likely to become the recommended purge duration.
