Soak the cashews in hot water for at least 45 mins.
Prepare the cashew mozzarella: Combine all ingredients in a blender. Transfer the mixture to a pan over medium heat. Stir until a stretchy cheese is formed. Transfer to a lined loaf pan and freeze a minimum of 3-4 hours.
Prepare 3 bowls: One with the batter, one with the starch coating, and one with the breadcrumbs.
Remove the mozzarella from the loaf pan and cut into rectangles. These should be slightly smaller than the size you want your mozzarella sticks to be.
One stick at a time, quickly coat in milk batter, in cornstarch, back in the milk batter, then in the breadcrumbs.
Transfer to a large pan and pan fry with a generous amount of oil over medium heat. once the bottoms are golden brown, flip and fry again until all sides are nicely browned and crispy.
Optional: Serve with marinara sauce.
Enjoy!
