why can’t you make cream by mixing (butter)milk and butter?

Question

Butter is made by churning cream, which causes all the fat molecules to clump together (creating butter) and leaves buttermilk as a side product.

Following this logic, why can’t you make cream again when you combine butter and buttermilk? Or even butter and regular milk for that matter

Answer 1

You can make cream with butter and milk. 2 parts whole milk, 1 part melted butter, whip until it forms soft peaks. Ideally, you’d want a stand/hand mixer because it takes quite a lot of whipping.
