Place potatoes, onion, garlic, scallion whites, vegan kimchi, gochugaru, ground turmeric, garlic powder, onion powder, cumin, cashews, and vegetable oil in a small pot over medium high heat.
Next, add the gochujang and stir until all the vegetables are evenly coated.
Deglaze the pot with the soy sauce and stir.
Add 1/2 cup water and bring to a boil. Cover the pot and lower the heat to low and let it simmer for about 15 minutes, until the potatoes are fork tender.
Add all the contents of the pot to a powerful blender. Add nutritional yeast, kimchi liquid, plant milk, lemon juice, maple syrup. Blend on high until smooth (about 1 minute on a high powered blender).
