Extremely fresh, all-natural, no additives and uniform size. Shells cleaned and graded, in natural delicious stock. Gourmet vacuum packed long-life New Zealand Green Lipped Mussels and Clams. They’re bagged in a USFDA approved, non-BPA plastic pouch. The pouch is then vacuum packed and pressure cooked at high temperatures in a retort (industrial pressure cooker). Each pouch comes with roughly 1 cup of delicious and natural clam stock. The Littleneck Clams are sourced from wild catch, quota managed fisheries in New Zealand’s South Island. They are swum in natural seawater to release any grit before being pouched and pressure cooked. Their natural flavors are retained while food safety and product shelf life are enhanced.
