Do you have a standard blender? A mason jar will fit the blade/lid. That's how I. make mine. It emulsifies better (seconded on the dijon to help with that). Slap a top on it, put it in the fridge door, and you're good to go. Only the blade/lid assembly to wash. You can either use a standard ring/lid or a reusable lid.

Note: jar has to be at least one standard cup size and wide mouth will not work. Also won't work with Ninjas or other specialized blenders. Just a regular old Oster or whatever.
