Lots of different opinions on shaping methods, which ultimately doesn't really matter. They turn out great whichever way you do it. Traditionalists roll a sausage and then join the ends. Lazy people, like me, punch a hole with a finger. Some people don't bother with a hole, preferring a bap like end product.
