Drain water from soaked cashews and add cashews, steamed cauliflower, hot sauce, salt, and nutritional yeast to a high speed blender or food processor
Blend or process until a smooth, even mixture remains - you may need to stop and start a few times and scrape the ingredients down the sides
With the blender or food processor running on medium slowly stream in oil from the top
Run the blender or food processor until all of the oil is incorporated into the mixture - you may need to turn your machine up to high to get a smooth and fluffy mixture
Remove the dip from the blender or food processor and enjoy!
