Congrats on your first attempt....for the skin, what I do is clean the skin first w/ just some hot water. Then dry it off...then get some type of cooking oil, I use olive, and some kosher salt. Rub the oil over the skin, making sure to get into all the wrinkles. Then spread the salt over the skin, and don't be skimpy with it. The salt will help draw the moisture out, and the oil will give the skin a great looking color. Then, just about an hour prior to the pig being done, go ahead and poke holes in it and let the grease drain out good. Once this is done, crank the heat up to about 350ish and let that skin crispen up....That should be all they wrote on that...
Good luck and take lots of pics...
