The word ua means to insert or fill in the middle. Sai refers to the intestines. Therefore, Sai ua means to stuff the intestines with something, which is a minced pork and chili mixture. This is a method of preserving food for 1-2 days. (Rattana Phromphichai, 1999, p. 7257). However, nowadays it can be kept longer in a refrigerator or vacuum bag.
