"...fried in beef fat and were made from just Idaho potatoes."
Exactly. Beef lard isn't all that bad for you. The veg. oil producers pulled a fast one on us and it hasn't been the same since.
We ought to go back to those old fries.
Try it sometime. Beef lard and Idaho spuds. A little sea salt and they are out of this world.
Mmmmmmmmmmmmmmmmmmm, the good old days.
