Why do my salmon fish cakes break up in frying?
In order to get fried cakes to stick together, they want to be cold when they go in to the oil. This allows them to congeal so that they are more solid. If you are leaving your ingredients out while frying or if there are warm ingredients giving off steam, this could explain the slow degradation with each batch. Once they're done in the food processor, put them in the fridge (or freezer) to cool them. Pull out just enough for a single batch at any one time.
