Ketchup is for fries because it implements salty and sweet...ketchup is basically sugar...
then you have a hot dog...a good quality dog...not that shit by ballpark...which is more of a sweeter meat combo...sweet on sweet is fucking gross...gotta have that salt...gotta have that brine...
the perfect stillz dog...is a Hoffman link dog, with a little bit of grill char...with mustard, onions, sauerkraut, and relish....

sauerkraut - brine
relish - sweet/crunch
onions - crunch
