Selecting Fresh Fish at the Market
The difference between a lackluster dinner and a vibrant one lies in the condition of the fish when you buy it. You are looking for a fish that still carries the vitality of the sea, free from any hint of ammonia or decay.
Trust your nose and your hands over the price tag.
Retailers often mask aged fish with ice or lighting; rely strictly on physical cues to determine quality.

What goes in.
- N/Awhole fish with intact skin and gills
Check the oxygen exchange
Lift the gill flap; the tissue beneath should be a deep, vibrant red or maroon. If it appears brown, gray, or slimy, the fish has been sitting too long.
The method.
Examine the eyes
The eyes should be clear and protrude slightly. If they are sunken or milky, the fish is stale.
Touch the flesh
Press your finger firmly into the side of the fish. It should bounce back immediately. An indentation that stays indicates the structure of the muscle has broken down.
Check the scales and skin
Look for a bright, metallic sheen. If the slime coat is thick, cloudy, or excessively gummy, the protective barrier is failing.
Assess the odor
A fresh fish smells like the ocean breeze or cucumber. Any sour, sharp, or ammonia-like smell is an immediate sign to walk away.
When it doesn't go to plan.
Buy fish that is lying on a bed of crushed ice, not sitting in a pool of meltwater.
If buying fillets, look for flesh that is translucent and firm, not opaque or separating into layers.
Ask the monger which fish arrived most recently; they usually want to move the oldest stock first.
The ones that keep coming up.
Is frozen fish always lower quality than fresh?
Not necessarily. Fish frozen at sea immediately after being caught often retains better texture than 'fresh' fish that has been sitting on ice in a shipping crate for five days.
