Blend Ingredients: Crumble the drained tofu into a blender. Add water, tapioca starch, nutritional yeast, lemon juice, salt, garlic powder, and onion powder. Blend on high until the mixture is completely smooth. If your blender struggles to blend the tofu smoothly, stop and scrape down the sides a few times.
Season to Taste: Give your vegan mozzarella a taste and adjust the seasoning if necessary. Consider adding a bit more salt, lemon juice, or nutritional yeast, depending on your preference.
Cook the Mixture: Transfer the blended mixture to a medium saucepan and cook it over medium heat. Stir the mixture continuously with a spatula or whisk to prevent it from sticking to the bottom and to ensure even cooking.
Thicken the Mozzarella: As you stir, the mixture will begin to thicken and start to look stretchy, resembling the consistency of melted mozzarella cheese. This process should take about 5 to 10 minutes. Keep stirring to maintain a smooth consistency.
Serve: Your tofu-based vegan liquid mozzarella is now ready to be used! It's perfect for adding a creamy, cheesy topping to pizzas, pasta, sandwiches, or any dish where you'd enjoy a melty cheese texture.
