When do you sausage experts use your fancy schmancy little sweetcorn holder/sausage poker gadgets? Do you poke the end of the casing before starting to stuff, then poke each air pocket as you see them develop? Or do you make it a practice to poke every sausage link several times for good measure. Just wondering. Maybe I'd better go find something constructive to do while my snack sticks sre doing their thing.
