Videos of people grilling ice cubes and seasoning them with sauces and spices have been doing the rounds on social media and leaving people with unanswered questions.

Move over, stir-fried stones, it’s time for grilled ice cubes to enjoy their time in the social media spotlight. According to several news reports from China, the bizarre street snack was made famous by a short clip shot at a street food stall in Nanchang, Jiangxi Province. In it, we can see large ice cubes being cooked on an open grill and seasoned with sauces and spices, before being served on a plate. We can’t see anyone eating the dish, but it is very popular on hot summer days, especially since it’s offered as a free treat.

After the original video went viral, Chinese news outlets managed to track down the street food stall operator and learn more about his popular dish. The man came up with the idea for grilled ice on a hot day, as a way to cool people off. It was meant as a joke, but people ended up loving it, so he kept making it. The bizarre street food doesn’t cost anything, but people wanting to try it – and there are reportedly plenty – have to request it in advance.

So should I eat it when it’s hot or when it’s cold? lol
