i stopped at our local pathmark, to pick up some cream of tartar to try,,  
found it in the spice aisle, in an tiny jar, (maybe 2 or 3 teaspoon jar),, for  
about 5 dollars,, is this the same stuff, if so this would be quite costly,, 
,,  and yes i know , if it works , it would be so cheap in the long run,, just 
want  to make sure i am getting the right stuff,,, because, i also seen cream 
of  tartar, in the mayonaise aisle , for a fraction of the cost..... thanks to 
all,  geo.
