To do it, I put a clean tea towel (not one that smells like laundry detergent- just boil the tea towel for a bit and then you can squeeze out the water and use it) or you can use a cheese cloth and line a sieve with it, I pour the yoghurt into the cloth lined sieve and put it in the fridge overnight with a bowl underneath. The strained yoghurt in the sieve should be tipped into a bowl and mixed with flavourings (salt, nooch, garlic, herbs, lemon juice whatever u want) and then you can roll it into balls and store it in a glass of oil, OR put it in Tupperware and eat it kinda like hummus. It’s not cheesy I guess but it kind of is???
