Getting butter from yogurt The common way for taking butter from milk is to shake the cream captured from milk. There is also a traditional way to shake yogurt to separate butter. However, I was unable to find any instruction for separating butter from yogurt.

Although, separating butter from high-fat cream is quite easy, but full separation of cream from milk at home is almost impossible. However, transferring milk to yogurt is quite easy. Therefore, there is an advantage for getting butter from yogurt (rather than cream), when the starting point is raw milk.


Why this method is not popular? Is there any drawback for that?
Where to find a practical instruction for this procedure? the
best temperature? using Greek (heavy) yogurt or adding water to
it?
I am skeptical that butter from yogurt is a thing.

When yogurt is made the milk proteins denature and form a mesh that traps all the large molecules in the milk. Water, sugar, and some small molecules can come out but the fat never does- it's huge and tightly bound up in the gel.

Even when yogurt is blended up the whey will separate out but the fat never does. I have a hard time believe that extricating the fat from that protein mesh will be easier than just letting it rise to the surface in milk.

Perhaps thoroughly cooking the yogurt would melt out the fat but you would still lose the rest of the milk solids and would have ghee.

With purchasable yogurt it would be even less feasible because it is often made from low-fat milk to begin with.

EDIT-

Searching online I was able to find Indian recipes for making butter from yogurt:

In this case they made yogurt from heavy cream. The goal was a cultured butter- not easier butter.
