Herta hot dogs are available in most of the supermarkets here in the UK. What I buy when I crave a hot dog. Tesco used to do an "american hot dog" that was quite good but stopped for some reason.
Canned hot dogs.....ick ick ick
Sauerkraut is also available in most of the supermarkets now. Usually in the section with the pickled onions, pickled beets and that lot. It's in a glass jar and so far, with all the brands that I've tried, it is never been sweet or saltly, just sour.
Costco hot dogs, Chicago style are lovely, but don't have give me heartburn. (My age I think.
) Just wish they would sell the hot dog buns there to fit the foot long dogs.
