It's called "VEGETALINA". It doesn't come in a tub like Crisco, but rather it is wrapped in a cross between the wrapping for a stick of butter and a thick aluminium foil. It is about as wide as a stick of butter by 2 1/2 to 3 sticks of butter deep by 1 1/2 sticks of butter tall. The wrapper is pedominantly white. It should be found near the butter area.
I first bought it a JUMBO, but then realized that my local chino also carries it.
Depending on what you want to bake, you can use either vegelatina like Napoleon mentiones, or also pig lard and cow lard which are also on the butter section. I rather use pig fat instead of veggie shortening or cow fat.
