alt Hacker News(I am from Eastern Europe). "Tvorog" / "Творог" is almost identical to commonly available cottage cheese. I buy the latter in big tubs from Costco and eat it almost every day for breakfast (with whatever fruits are on hand, or with raisins and nuts in the worst case).
Yeah, I actually learned how to make it myself, although it requires access to kefir/piimä, or making it yourself first. Once you have it, it’s very easy to make it, although often unnecessary when local eastern shops have it quite cheap.
Not sure about availability in the US, in EU cottage cheese often is sold as much more creamy spread, like Philadelphia cheese.
