I hate to admit it, but I'd never heard of pork cracklings before today. Looked it up on Wiki, and now I want to try them -- sounds really good! Unfortunately, I live in NYC, so finding them probably won't be easy; even when I'm snacking on Cheez Doodles or the like I get glares from some people like I'm clubbing a baby seal. Yummmm...seal cracklings! :-)
Go to a specialty meat store and ask for pig skin, than take it home and deep fry it. I like mine with tons of Sriracha hot sauce.
The stuff you can buyat the store (at least in the mid-west) is a poor substitute for the real McCoy. The commerical stuff is sorta like eating styrofoam - lots of air and no taste. Homemade crackings are chunks of pigskin carved up, covered with salt and thrown into a kettle of boiling lard. That’s good eatin’.
