Boil the cashews for about 10 minutes until soft and tender, or soak for 2 hours if using a high-speed blender
Add all cashew base ingredients (softened cashews, water, arrowroot powder, garlic powder, salt, lemon juice, apple cider vinegar, and nutritional yeast) to a high-speed blender and blend until completely smooth
In a saucepan, whisk together agar powder and water
Heat the agar mixture over medium heat, stirring constantly, until the mixture thickens and becomes glossy
Carefully pour the hot agar mixture into the blender with the cashew base
Blend again until fully smooth and well combined
Pour the mixture into a silicone container or mold
Let cool at room temperature, then refrigerate for 3 to 4 hours until firm
Once set, you can grate, slice, or use as desired on burgers, pizza, sandwiches, or crackers
