Soak, drain and rinse the cashews.
Place the cashews in a food processor along with lemon juice, salt and black pepper.
Pulse for about 1 minute to combine the ingredients.
Add the water and process until completely smooth, about 2 - 4 minutes.
The longer you soak your cashews the more water they absorb. If you soak your cashews for an hour you won't need to add additional water. If you’re in a hurry and only soak your cashews for 10 minutes, you may want to add a few extra tablespoons of water.
