1/2cupyogurt with live culturesI like Total or 5 grams packaged yogurt starter
Heat the milk in a heavy bottomed pot on medium heat until the temperature reaches 180F. The milk will look like it's just about to boil. Use a digital thermometer to check the temperature, and stir before you check it.
Take off the heat and let the milk cool to 112F.
Whisk in the yogurt or starter, make sure it's completely mixed in, and then either pour the milk into your yogurt machine, or set the pot, covered, in a warm spot for about 4 to 6 hours. You can try inside an oven with a pilot light, or on a counter wrapped in a heating pad or electric blanket on low. Don't move, stir, or disturb the yogurt while it sits.
Refrigerate the thickened yogurt overnight, and then enjoy.
You can use low fat or even skim milk, but you may need to add powdered milk or even gelatin in order to get a thick final product.
