I have a small Cuisinart Mini-Prep that I bought about 10 years ago that looks like a junior version of my 25 year old original Food Processor, and about two years ago received a new space-agey looking model as a free gift with something I bought at Macy's. But I never even got it out of the box, presuming it was identical except in looks and possibly not as good mechanically.
Never got it out of the box until today, that is, because a friend needs one to grind home-made cat food in and I want to give her one of mine.
It was instantly obvious that the bowl of the new one is slightly larger (by maybe 6 ounces) and slightly flared in shape, like a winsor sauce pan, where the other was a straight cylinder. But more importantly, the blade is quite different: high on one side, lower on the other, and angled--this blade looks like it will lift while it chops, and that will resolve my complaint about the old baby Cuise, which I tend to use only for liquid-based blends because solids get packed on the bottom.
This called for a test, so I loaded a handful of walnuts into each and ran them for two 4-second intervals. Bingo--the improvement was evident after each interval. There was more consistency in the new unit after four seconds and only a few medium chunks left after eight, where the old unit after eight had fine powder and a large number of big chunks that had just flown around the top of the unit while the blades busied themselves packing everything else beneath them.
The next benefit was obvious when I removed the blades and dumped the ground nuts out--the old Cuise had more ground nut mass packed into the base of the bowl. Though the quantity of nuts was only about 1/8th the capacity of the bowl, the old Cuise could not have handled a larger quantity without making nut butter in the bottom of the bowl. The new one obviously could.
So which to give away? Neither--keep the new one, and take Vanessa shopping for one just like it!
