For the fish cakes, place the fish, fish sauce, red curry paste, lime leaf, galangal, lemongrass, coriander root, egg, palm sugar, beans, and lime juice in a food processor and blend to a paste.
If the crab cake is trying to fall apart, use your hands to press any stray pieces back in and pack it more firmly into the scoop next time. Do not flatten. Space at least 2” apart on baking sheet.
If your sauce is too thick, add water to thin, about a teaspoon at a time. Poach the eggs in simmering water. Place one crab cake on each plate, top with poached egg, then sauce.
