36F)

7. CONCLUSION
• Preparing fish and shellfish requires working
knowledge of the characteristics of the types
available. This is an ongoing and never ending
endeavor since many new varieties keep coming into
the markets regularly, presenting a great challenge
to the culinarian. This challenges the chefs to
determine the suitable cooking method for each new
variety being introduced.
• Farm raised products often have flavors and
textures different from their wild counterparts.
• Nutritional concerns increasingly direct chefs
towards innovative preparation techniques and
rethinking of traditional cooking methods.
