A tip, Tip Speed.
Do you use a stick blender?
It occurred to me that I can share this tip with you:
What makes a blender work is the difference between the speed of the blades' tip and what you are trying to blend. The bigger the difference, the better the end result. An expensive counter top blender can achieve over 30,000 RPM.
A hand stick blender cannot go very fast because of portability and low power. Most of them are about 15,000 RPM. A stick blender goes much slower inside a liquid, especially thick liquid, probably less than 8,000 RPM.
You can get much better end results for blending if you try this technique, even with blending a thick liquid:
With the blender turned on, insert the blender in and out of the liquid. When the blender is out of the liquid, it achieves max blade speed immediately. When you plunge the blender at max speed into the liquid, the liquid is at 0 speed, maximum blending occurs. Very quickly, the blade slows down by the liquid, then you lift the blender out of the liquid again. In and out, in and out, keep repeating.
