If you can boil water, you can make yogurt. If you can't, skip down to crme frache. Otherwise, what you will need for this is a big pot, an instant-read thermometer, a colander, some cheesecloth (available at most grocery stores look near the disposable roasting pans), and a clean dishtowel. It needs to sit in the oven overnight, and then drain until it gets as thick as you like it. Be sure to use a good quality commercial yogurt as a starter look for one with live cultures.
