Sa Giang shrimp crackers (Bánh phồng tôm) are a renowned Vietnamese specialty that has been famous domestically since the 1960s and is now exported to over 30 countries. Made from a time-honored recipe using locally sourced freshwater and saltwater shrimp—such as giant river prawns, whiteleg shrimp, and iron shrimp—combined with high-quality tapioca starch from the Mekong Delta, these crackers offer a distinctive sweet, umami-rich flavor and a delightfully crispy texture. The dough is skillfully prepared, steamed, sliced into thin rounds or squares, and thoroughly dried into hard, translucent pellets that puff up instantly when deep-fried for 5–10 seconds or microwaved for about a minute. While the classic shrimp version remains the flagship, Sa Giang has expanded its product line to include crab, cuttlefish, seafood, and vegetarian options like sweet potato and vegetable crackers to cater to diverse global tastes, with shrimp content ranging from 10% in standard varieties to 30% in premium square versions.
