No, it's not borscht. That's showing them making polish cabbage rolls. The beef pork, onion mix is being cooked in a pot, gets mixed with rice and then wrapped up in cooked cabbage (some people freeze it instead to make it rollable) and then are slow cooked in a tomato sauce.

It's a lot of work, which is preferably done by a group, which I believe is further allusion by the Ghost meme.

In the US they're called halupkies.
