This is an awesome snack. It took me 3 hrs to de-hull the peanuts and it was well worth it :)
One thing though, forget the peanut oil, Roasting in the oven is healthy enough v deep frying so use real lard. When I used peanut oil nothing wanted to stick to peanuts.
And when I say real lard I don't mean that industrial pure white stuff you can buy at the supermarket. Buy some fatback, slice the skin off, cut it into 1x2" rectangles and and make some chicharrones while you're rendering the lard from the cubed fat too :)
