Where can I find it, what does it look like (the packaging)?
look for this
in the cake/sugar aisle ....usually a top shelf item.
It's right next to the Jello at most stores. The Knox brand box is white and orange.
I find that it stinks when mixed with water, if that matters.
It stinks because it is derived from meat.
It stinks because it's meat! Gelatin is the grosset thing ever. I wouldn't use gelatin or Jell-o in a cake even if I got paid!!
