Outside of Lithuania, you can find the authentic curd cheese in Lithuanian or most Eastern European ethnic food stores. While living abroad, I have been usually replacing it with cottage cheese. Cottage cheese has more moisture and a different texture, so the recipes needed a bit of tweaking. My cookbooks contain these customized recipes that use cottage cheese.
