Then you want to have a bowl that will hold the colander and have plenty of room for the whey to drip into. You will be amazed at how much whey will drip out.

Then add the yogurt and place in the fridge for 24 hours to drip:
Then scrape the "cheese" into a bowl and it should keep in the fridge for up to two weeks. Two quarts of yogurt will make about two and a half cups yogurt cheese.
