Do you grill sausage with casing on?

Chef's answer
Don't break or score the casing As Standing says, "That casing is holding in all of the juices and fats and all the stuff you want in there." Scoring the sausage not only allows the fat to escape, that lost fat can cause flare-ups which will char your sausage on the outside before the inside is completely cooked.

All sausage casings are safe to eat. If it is a natural casing it is truly edible, and intended to be eaten. If it is a plastic casing, well I wouldn't recommend it, and you probably won't do it twice, it but it should be medically safe for a healthy adult so long as you don't choke on it..
