Som moo is a Laotian fermented pork sausage that is adapted from a traditional celebratory Vietnamese dish of the same name (translated as sour pork). It can be found in most Southeast Asian supermarkets and local eateries, and can be consumed by itself as a snack, or used to create other dishes, such as nam khao (rice ball salad).
The process of making som moo involves mixing minced pork and pork skin with garlic, sticky rice, chili peppers, and salt. The concoction is then wrapped tightly in cling film and left to ferment at room temperature for about 3 days. After the fermentation process, the dish is ready to be served at weddings, family gatherings, or similar festive events.
