Makes two Mason jars (1 litre size)
- 8 cups cow or goat milk
- 6 tablespoons yogourt (unflavoured, unsweetened, with active bacterial culture. I use Astro)
Spoon Astro yogourt into a dish and set aside to warm up.
Heat milk to 180 degrees (13 minutes in my sold, slow microwave), then let cool to 110 degrees. (approximately 20 minutes)
Remove a cup of warm milk and stir in Astro yogourt.
When the milk is 110 degrees, add the Astro / milk combo and stir well to combine.
Pour liquid yogourt through a strainer lined with cheese cloth to remove lumps, then ladle into prepared jars (I use Mason jars).
Wrap jars in a towel, place them together in a box (I use a picnic hamper), then place the whole thing in a cold oven with the light on.
Leave 8 hours or overnight.
Remove 6 tablespoons of yogourt and set aside to make yogourt next time.
Chill yogourt 3-4 hours then serve.
