Cashew Cheese Sauce

Rinse cashews under warm water. Place in a bowl and cover with hot water. Let soak for 10 minutes.

Combine 2 cups water, nutritional yeast, cornstarch, and mustard in a blender or food processor. Blend on high for 1 minute. Add soaked cashews and blend on high until smooth, 1 1/2 minutes or longer. Transfer to a medium saucepan.

Cook over low heat, whisking constantly, until sauce thickens, 5 to 7 minutes. Add more water if needed to reach desired consistency. Season with black pepper.
