I just bought an Immersion Blender, specifically for mashing Cauliflower. I absolutely love it! It makes mashed Cauliflower as smooth as mashed Potatoes, in no time I am going to use it for mashing Butternut Squash, too. I always make mashed Rutabaga, but with this type of blender it should give me a smoother/creamier consistency instead of the slightly lumpy I get with a hand held mixer. I will use it regularly.
