Yeah, certain varieties of La Gao Ma brand la jiao (which is one of the most ubiquitous varieties around here, i.e. in Australian Chinese diaspora supermarkets) contain pork! Unhappy surprise for the vegetarian. The peanut version is tasty, though, and vegetarian-friendly. My family tend to eat it mainly with dumplings and soup noodles-- I like fresher chilli sauces for other things.
