Blender

I have a Vitamix and it is used every day, whether it’s just to make a smoothie or to puree something smoother than a food processor could get it (like nut cheeses or ice creams). The Vitamix is pricey and definitely an investment, but if you plan to do a lot of blending, it’s totally worth it. A regular blender may work as well, but you may need to soak nuts longer or plan for a possibly less smooth consistency.
