Roasted Chestnuts were among the many street snacks I had in Hong Kong, along with Fish Balls, Cart Noodles, Wonton Noodles, and Put Chai Ko.
Most interesting street snack tried in HK: deep fried pig intestine, skewered on a stick
I did NOT attempt to have stinky tofu again (fermented tofu are cut, skewered on a stick, and then deep fried. It’s revolting!). That remains a black eye from my Taiwan night market experience. My nostrils are still recovering.
