One gallon of milk to boil (whole milk!), bring to a boil. Turn off the fire. Let it cool down to the temperature where your finger can be comfortable in it. Then, 2 cups of plain yogurt, then take 2 cups of the warm milk. Mix together and then put it back in the pot with the rest of the warm milk.
Heat your oven to the smallest temperature you can do it. (200° F). Then once it's at 200° F, shut off the oven, then place the yogurt into the oven overnight. The day after, put in the fridge, let sit for a couple of hours (to chill), then strain with a cheese cloth.
