A friend of mine who lives in Lebannon, PA talks about eating something similar but they don’t call it "pounce." I think they just call it stuffed pig stomach. I’ve never had it but I imagine the cajun version of it would be the best. If it comes from Southwest LA, how bad could it possibly be?
I tend to agree with the immortal words of Nathan and the Zydeco Cha-Chas who sang, "Everything on the hog is good. ‘Cept the eyes. The eyes ain’t no good."
