I just read this... most regular blenders will accept Mason jars, so you can grind spices or your coffee beans into a Mason jar, and store right away. Simpler clean-up, no need for separate coffee or spice grinders, or to buy one of those 'bullet blenders'. It's also good to know if you happen to break the that jar/lid that comes with your blender. (see clarificiation in"more info", following comments rec'd.)
Clarification following comments: I take my blender's blades and screw them onto the jar, then screw that into the blender stand. Hopefully that's clear?
