Chili crisp
Chili crisp, chile crisp or chili crunch is a type of hot sauce, originating from Chinese cuisine, made with fried chili pepper and other aromatics infused in oil, sometimes with other ingredients. Multiple regional, homemade, and restaurant-original versions exist across China. The best-known commercial brand is Lao Gan Ma, which is based on the chili crisps of Guizhou province. The chili crisp is closely related to Chinese chili oil, and sometimes the two terms are used interchangeably, the difference being that the crisp contains edible chunks of food in the chili oil. Infused-oil hot sauce condiments have been made and used in China for centuries and multiple regional variations have developed over time. In southern China it is more common to simmer the ingredients in the oil, while in the north it is more common to pour hot oil over the ingredients. Households and restaurants developed their own versions, and in China "almost every restaurant makes their own",[dubious – discuss] according to chef and restaurateur Lucas Sin.
