Where's the video on how to make Yogurt Starter?

You just use your last batch to start the next one, so that is really what this video is showing. Yoghurt starter is just live yoghurt, so first time around you can use store bought live yoghurt or buy starter powder.

Used to make it alla time-Half-gallon atta time.
Whatever type of yogurt is your favorite, buy a single container of that kind, plain.

Add one heaping spoonful of yogurt to milk that has been heated to just prior to boiling and cooled to b/t 105 and 112 F-Maintain that temp range over night and, voila.

(If you want your yogurt a bit stiffer add to your whole milk, about 2/3 c dry milk , or maybe some agar agar if you prefer.)

I like mine runny, so I nix any thickeners-Whole, organic milk and really really good Greek or premier yogurt-

Hint: Your conventional oven will maintain a perfect temp, by simply putting a 40-60 watt bulb in with the closed oven (small lamp). Most ovens won't adjust to maintain a low temp below 200 degrees all night.
