I've made a few batches now and it's really a simple process:
1 quart whole milk (you can use pasteurized or raw, but not ultra pasteurized)
1 tablespoon organic yogurt (from the store) or 1 packet of yogurt culture starter
1 teaspoon gelatin
1/2 cup white sugar, sucanat, or honey (your choice)
Heat the milk to 180 degrees on the stove in a stainless steel pan. Use a candy thermometer to watch the temperature. Stir frequently.
When it reaches 180, remove from the heat and let it cool back down to 105 degrees. Tip: Place your pan in a sink of cold water. This speeds up the cooling process a LOT.
Add the gelatin and whisk in vigorously. Make sure the gelatin is completely dissolved. Add 2 tablespoons of organic plain yogurt (or 1 packet of yogurt starter) and gently stir. (You want to be less vigorous with the cultures). Add the sugar, sucanat or honey and stir well.
I strain this mixture through a sieve into a large measuring cup and then pour into 6 half-pint jars. Cap the jars and place in your dehydrator. (Preheat the dehydrator a few minutes at 115 degrees).
Six hours in the dehydrator seems to be the perfect time for my yogurt. Remove from dehydrator and refridgerate. Enjoy!
