The tradition got a boost from Prohibition-era taverns, which served cheap fried fish to stay open and draw crowds, then kept the Friday ritual alive long after Catholic meatless-Friday rules eased.
Beer-battered cod or perch is deep-fried and served with coleslaw, rye bread, and tartar sauce, dished up cafeteria-style at supper clubs, taverns, and church halls every Friday night. Portions are typically all-you-can-eat.
