Last night, I took a baggie of heavy cream into the club and danced around a lot. My goal, obviously, was to see if this method yields butter. At the end of the night, the baggie was warm. it had separated and turned into this. (Soft peaks?) I poured off some of the buttermilk. You can see the buttermilk in the bag
In the morning, the baggie is solid. Stored in fridge. My friend is using a bit of it to cook. Is it butter? Is it cream? I don’t remember it going through any “butter” stages. But why is it solid?

Update: i took it out of its bag, washed it in ice water, and packed it up in plastic wrap. It is now thawed and still sitting pretty. It’s definitely butter!
