In Turkey, kashk is a dried yoghurt product also known as keş peyniri, kurut, taş yoğurt, kuru yoğurt, or katık keşi.
In modern Iran, kashk is a thick whitish liquid similar to whey or sour cream, used in traditional Persian cuisine like ash reshteh, kashk e badamjan, kale joush. It is available as a liquid or in a dried form, which needs to be soaked and softened before it can be used in cooking. Kashk was traditionally produced from the leftovers of cheese-making .
