Make the cheese: In a blender, combine the drained cashews, water, sauerkraut, yogurt, coconut cream, and salt and blend until smooth, about 60 seconds or longer, depending on the strength of your blender.
Add the coconut oil and process again until very smooth. (It’s important to add the coconut oil after blending the initial ingredients to prevent it from hardening in the blender, which can happen if the temperature of all the other ingredients combined is below 76°F/24°C.)
Using an instant-read thermometer, make sure that the temperature does not exceed 110°F (43°C) after processing. If it does, allow it to cool to that or below, then add an additional 2 tablespoons yogurt and very briefly blend to combine.
Pour the mixture into the sterilized mason jar, secure with a lid, then set in a warm place (ideally between 85° and 110°F (29° and 43°C) to ferment for 12 to 24 hours.
The warmer the temperature, the faster the fermentation. Suggested places are outside on a warm day, in a sunny window, near a fireplace or in a yogurt maker or an oven with the light turned on.
Taste after 12 hours to see if it has achieved the desired tang of goat cheese. Transfer the container to the refrigerator and allow it to set for a full 24 hours.
