I've never cooked with lard, and am not sure I would even know where to find it in the supermarket.
But considering all the supermarkets around here stock all of the necessities (large mexican population) I guess I could break down and ask - and make my next batch with it and not the Crisco I usually use.
In the grocery store, it's usually somewhere in the vicinity of the butter!
I use it on occasion - makes the best biscuits you've ever tasted, and it's also good in refried beans, odd as that sounds.
Not that I know how to make such things properly, Scots-Norwegian Yankee that I be...but someone taught me to make 'em that way and I do it once in awhile!
Lard will most likely be next to the butter, sold in a box shaped just as if it were a box of four sticks of butter. I've seen it in tubs, too, but not nearly as often.
Here there are boxes with two shades of blue --- Morrell Snow Cap Lard --- they sell it everywhere but this is the border which might be why it's so common. I think it makes a real difference but then that's how all the mexican food is made here.
I haven't cooked with it in ages, before my mother passed away, we would cook with it occasionally. I just bought some recently, by coincidence. It keeps well in the fridge. I found it in the section by the butter, but that was in a corner grocery.
