Cover cashews in plenty of water and let soak for at least 2 hours. OR if you want to make this right away, boil the cashews for 10 minutes until tender.
Drain your cashews and toss them in a food processor with everything else. Blend it all up, stopping to scrape down the sides every now and then until you reach your preferred ricotta texture.
Notes
Soy-Free: To keep this recipe soy-free, swap out the miso for chickpea miso! Also, use an almond milk or oat milk instead of a soy milk.
