Soak walnuts in a bowl of water for at least 4 hours or overnight.
Drain and rinse walnuts.
Place into a food processor or blender with remaning ingredients, except for the probiotics.
Blend until uniformly smooth.
Remove blade, and empty the probiotic capsules or powder into the mixture. Stir with a woodern or plastic spoon (no metal).
In a shallow glass or plastic dish, place a large square of cheesecloth or thin fabric. Pour the cheese mixture into the center of the cloth.
Gather all ends together and twist until it forms a round/circle. Keep the covered cheese round on the dish. Cover with a dishcloth and set in on the counter away from direct sunlight.
Let ferment for 48 hours.
When 48 hours are up, place into the refrigerator for at least 4 hours (up to 8) to chill and firm up a bit.
Remove from the fridge and gently peel away the cheesecloth or fabric. Optionally, you can reshape the cheese with your hands by ‘hugging’ the cheese with your hands.
Place on a serving platter and optionally sprinkle with red chili flakes and finely minced jalapeño before serving or place in the fridge in an airtight container for up to one week before serving.
