Description
Sauerkraut on a hot dog isn't just a topping — it's the combination that defined New York City's street cart culture since German immigrants put it on a frankfurter in the 1860s, and the air fryer version gets you there in 10 minutes. This is the complete guide: the draining step most recipes skip, the right mustard, and the caramelized onion upgrade that makes it actually taste like a New York street cart.
