Step 1
Puree shrimp in a food processor (smaller is better) until you have a smooth paste or chop and mash by hand. Add fish sauce. In a bowl, mix the shrimp purée, crab meat, egg, scallion, cilantro, chili, ginger, and salt and pepper; add just enough bread crumbs to stiffen mixture a bit. Refrigerate mixture until you are ready to cook; it will be easier to shape into cakes if you refrigerate it for 30 minutes or more.
