What the hell is "fish dip" ?? If it's really a thing, it needs another name!
Do you seriously not know what fish dip is? Maybe it's a Florida thing. I thought it was more ubiquitous.
Down here, the kingfish that run in the winter are excellent for smoking and making into dip. I'm pretty sure there are dips made from other fish, such as trout. You can find fish dip at almost any seafood store or shop.
