i like a good natural casing, but its a fine line between having a snap, and being too tough to break through with your teeth. i like the ‘bite of dog’ to snap, then break free cleanly, not with some chewing of the casing, to get free, before the rest of the dog comes sliding out of the but, throwing toppings all over the place. oru local home depot has a vender, who soakes the dogs in water (boils them) so long, that i can taste the metal pan of the steamer in the juices. that, is a travesty. but i guess alot of folks have no taste buds, as the always seem busy.
