3. Fish has very little connective
tissue. It means that….
• Fish cooks very quickly even at low
temperatures
• Fish is naturally tender and needs no
marinating
• Moist heat cooking methods are best
• Handle cooked fish carefully it is delicate!

4. Doneness and Flaking
• When fish is cooked the flesh naturally
breaks apart into separations this is called
flaking.
• Be careful not to overcook flaking should
not be falling apart.
• Pay attention to carry over cooking.
• Fish is done when it is opaque and just
beginning to flake.

5. Cooking fat and lean fish
1. Lean (low in fat) fish is flounder, sole, cod,
red snapper, bass, perch, halibut and pike.
– Can become dry so poaching maintains moisture.
– If you use dry heat cooking baste with butter or oil.
2. Fat fish is salmon, tuna, trout and mackerel
-Poached salmon is popular
-Dry heat eliminates excessive oiliness
