Sorry for the late reply.
I am not a snoot expert, but here is what I know....Snoots taste kind of like a super pork rind in bbq sauce. They have been really popular for a long time in the small BBQ joints in the African American communities around St. Louis and East St. Louis. Their popularity has spread into a lot of the St. Louis metropolitan area. I have some friends who like to cook them. They cook the fatty, cartilage-like pieces until very crispy, then dunk in bbq sauce immediately before eating. A good snoot is crunchy, porky, saucy, bbq goodness, with a strong pork flavor. A bad snoot is rubbery and kind of nasty tasting.
My first snoot experience was in East St. Louis... I was a teenager, setting up a sound system in a church. I asked a guy what he was eating and he said "snoots, you want one?" I eagerly accepted and raised a saucy piece to my mouth to take a bite... My front teeth bit down on the snoot, and nothing happened. Laughter filled the building as I, the confused white-boy, tried to bite off a piece. "You gotta use your back teeth," a guy said. I moved it to my back teeth and chomped away. After seconds, and thirds, I was hooked.
Gladly, my first snoot was a good one. It wouldn't have mattered...My motto: I'll try anything twice.
