Sabrett makes a great hot dog. They are excellent in water as well as on a griddle. For some reason, the 8 to a lb natural casing dogs aren’t packed as tight as the smaller ones. I prefer the 10’s for their texture. Unfortunately, they are only available at Restaurant Depot or a Sabrett distributor.
For cooking in water, bring a pot of water to a boil. Shut off the gas, put the dogs in, cover the pot, and let sit for 10 minutes. The dogs will be just the right temperature and will retain the snap. For grilling, I would place on a griddle and cook until well done and crispy.
