By golly, you revived an old memory. Grandma did use Crisco for fries. Mainly used it to make the most wonderful flaky pie crusts.
I wonder if the composition of Crisco is the same now as it was then.
FWIW, elcid... I use crisco for my pies and if you ask around these parts... the pies are very good. Flour, a little salt, Crisco and ice water to make the crust...
