Thai Style Crab Cakes

This is a formidable crab cake in a style that mimics tod mun, the Thai fish cake that, when made right, packs astonishing flavor. These cakes require shrimp purée as a binder; scallops will also work in place of the shrimp. Just stick a few in a small food processor and whiz for a few seconds, or chop and mash by hand.
