If you plan to buy only one book on seafood, make it this one. It is by far THE BEST book around. Rick Stein cooks simple, clean yet unbelievably flavoursome seafood ever. There are 3 parts to this book - Techniques, Recipes and Information. In part one, Rick's clear explanations supported by good close up shots of how to prepare various seafood from skate to scallops is simply indispensable.
The second part is all about recipes - mothwatering stuff here, be warned. There are traditional dishes, with or without a modern twist as well as exotic consoctions from Asia and Africa. No fish is spared the Stein treatment: he works his magic on skate, cod, eel, sardine, monkfish, bass, herring, smelt,mullet, mussels, oysters, scallops, squids etc etc etc.
And finally, part three has enough info on seafood that will allow you to impress a marine biologist at the dinner table. And for the rest of us, Rick has included some basic recipes such as home-made mayo, italian salsa verde, lemobgrass butter etc.
This is a good honest book. Buy it.
