Hot and Sour soup, though a regional dish originating in Sichuan, is a staple today in almost all Chinese restaurants. This one is brimming with pork, tofu and exotic Chinese ingredients and achieves the nuanced but necessary balance needed to make it memorable. The dominant flavoring elements of vinegar, hot chili peppers and copious amounts of black pepper used in just the right proportion produces a great soup, and to do it the same way every time with such aggressive flavors is no easy task. Here, they have mastered it. I never visit Towson Best without ordering it.
