Pour four cups of nut milk /w protein into a quart-sized glass jar.
Sprinkle the entire contents of one Easy Kefir packet into the jar and mix well.
Put a lid on the jar.
Let this mixture ferment at 72° to 75°F for 18 to 24 hours. If the temperature is below 72° let it ferment a little longer.
Place into the refrigerator. Even in your refrigerator the fermentation process continues, but chilling it will slow down the fermentation of the healthy bacteria and beneficial yeast.
See note below on re-culturing your kefir to make new batches!
