I'll bite - I'm experimenting more in the kitchen now, so how do I make some (Primal community approved) yogurt?
Take raw milk, heat it up to about 120-123 degrees, then let it cool to 110 degrees. transfer to a crock pot, add in some plain yogurt (your "starter) mix thoroughly. Wrap crock pot up in big towel or blanket. This is to keep it at a steady temperature. Place somewhere warm (I put mine in the same room as the wood burning stove, but if you wrap it well, you can keep it anywhere that is warm in your house. Let sit over night, 8-10 hours. Take the lid off and voila! Yummy yogurt!
