Have you put them in a pot of water and heated the water slowly? Do not boil the water, just let the dogs sit in the hot water until they get warm. What you’re trying to do is “steam” the dogs.
steaming in an actual steamer is probably a better idea- I can’t imagine Costco selling an undercooked item (warm water?)
Steam will heat it hotter than boiling, but not boil away the flavor
Also, make sure you buy the same dogs they have- they may not be the same. You gotta have a good product if you are going to sell them for $1.49
My favorite way is BURNT BEYOND RECOGNITION!
if you just put the dogs in the hot water without boiling, do they cooK???
thanks
maybe there is a “hot dog steamer” machine for sale on the internet?
