@Eva,
It's never the engineering department's fault, it's always the marketing department's. "More BELLS more whistles!"
Wait.
I'm changing my mind. Engineers are always too willing to give in to the marketing department's demands.
If only once they would say "Nope, we can't find a way to put anymore bells and whistles on that thing."
But, they always can and do. So..... here is a blender.
It has eighteen , count'em, !
eighteen! speeds.
PLUS "pulse" on every speed. Ain't it grand?
Mr. Waring's first effort had two. High and Low. It made gimlets and smoothies very very well. Later, er, research revealed it's ability to create superb Margarita's.
If it was possible to go into everyone's kitchen and look at the buttons on their blenders, I'm betting that that research would show maximum use of only two buttons: the slowest (mixing the olive oil into the pesto or the butter in the Hollandaise sauce) and HIGH (everything else.)
Joe(ut-oh,,,now I have the need for Eggs Benedict...)Nation
PS: one should NEVER make Hollandaise Sauce in a blender. Never.
