Re:Way beyond a corn dog...
It reminds me of a comestible served in certain delicatessens on the East Coast years ago--- known as hush puppies...and not to be confused with the Southern specialty of little, deep-fried cornmeal breads.
The Jewish hush puppy was a hot dog encased in a cylindrical knish. I'm told the Knish Shop in Maryland still makes a variation on this item, the hot dog peeking out at each end.
Sabrett advertised all over some arenas their coming introduction of a similar item....and it just never happened. And absolutely no one knows a thing about it.
In any case, this looks good...bring it on...hopefully
not frozen. And yes, indeed, the muddling of the mustard vs. ketchup issue is an astute point.
