Soak the raw cashews in very hot water for 15 minutes to soften, then drain and rinse.
Remove the tofu from its packaging and press firmly with a clean towel to remove excess water.
Crumble exactly half of the tofu block into a medium mixing bowl using your hands to create small, curd-like pieces.
Place the remaining half of the tofu block into a high-speed blender or food processor.
Add the soaked cashews, nutritional yeast, hemp hearts, lemon juice, sea salt, onion powder, and water to the blender.
Process on high until the mixture is completely smooth and reaches a thick, pourable consistency.
Pour the blended cream over the crumbled tofu curds in the mixing bowl.
Fold gently with a spatula until the curds are evenly coated and the mixture resembles cottage cheese.
Serve immediately or refrigerate for 30 minutes to allow the flavors to meld and the texture to firm up.
