Mix together the yogurt and the salt
Layer a large bowl with cheese cloth, a linen, or a towel
Pour the yogurt over the cloth
Tie all ends of the cloth together, creating a not over the yogurt and ensuring it is fully covered
Tie the cloth from the kitchen sink faucet, allowing to hang and drain excess water into the sink OR place cloth into a strainer over a small bowl and place into the refrigerator
Allow the yogurt to strain for 24-48 hours (I only did 24)
After at least 24 hours, unwrap the yogurt from the cheesecloth and you will have thick, spreadable, "yogurt cheese"
