Historical information
Early settlers had to be self sufficient, growing their own vegetables, making tools and clothing and usually had a house cow to produce their milk supply. .All the buttermilk separated from the butterfat had to be rinsed out. This would improve texture and flavour, and also help the butter keep well, since milk turns rancid more quickly than fat alone. Salt was usually mixed in at this stage - for flavour and preservation. The rinsing could be done simply by washing in water, followed by draining, salting and working or "kneading" the butter with a pair of wooden butter pats, or with bare hands.
