Sure. But, not for years.
When I was a kid, we had milk cows, and if I put those two words together, milkcows, the autocorrect on my electronic device wants to change them to "millions!"
Well, we seemed to have millions of cups of milk. If you allow that milk to sit, cream separates and rises to the top. We could also use a cream separator but it wasn't run by electricity ...
Anyway, several cups (a gallon!) Of that cream could be poured into a square glass churn and the handle turned until the butter separated out as little clumps. If you then poured the contents of the churn through a screen of some sort, we used a threadbare dish towel, you could squeeze the clumps together and - there you go.
Cartoons were on teevee, we would use two quart canning jars instead of the square glass churn because they were easier to hold while sitting on the couch. Shaking and shifting the cream in the jars works the same as churning it and, if you are watching teevee, it's nearly electronic ...
NyBoy, you should know that fresh butter has very little flavor. I suppose, at most, it tastes a little like clover. Ours did, anyway ... everything about our cows tasted and smelled a little like clover, their milk, their meat, even cow burps!
Anyway, butter is like cheese and develops flavor as it ages. Like me! Some of us go rancid but young women now hold doors for me! I'm looking forward to a time when they call me "sweetie!" A little salt may help the process ...
