White Fish
Flavour Profile
Mild, delicate and slightly sweet. White fish isn't there to dominate; it's there to carry other flavours.
It has a clean finish that makes it the perfect partner for bright acidity like lemon and capers, or punchy aromatics like ginger and chilli.
Health Benefits
Good protein, and a decent hit of iodine, which your thyroid needs to work properly. Not much fat in it, so it's lean eating.
Buying Tips
Look for firm, translucent flesh that doesn't look chalky or dry. If buying whole, the eyes should be clear and bulging, not cloudy.
Fresh fish should smell like the ocean, not like 'fish'. If it has a strong, pungent aroma, it's already on its way out.
Storage
Fish hates sitting in its own juices.
If you aren't cooking it immediately, pat it dry with paper towels, wrap it tightly in cling film, and sit it on a bed of ice in a container in the coldest part of the fridge. Aim to cook it within 24 hours of purchase.
Cooking Uses
White fish is the ultimate blank canvas. It can be flaked into tacos, dipped in batter for frying, or poached gently in olive oil or coconut milk.
Because it lacks fat, it cooks very quickly. It is done the moment the flesh turns opaque and flakes easily with a fork. Overcooking turns it from silk to sawdust in thirty seconds.
Forkin' Food Theory
White fish has a 'short-muscle' structure compared to land animals.
In a cow or a pig, long fibres are held together by tough connective tissue called collagen, which takes time and heat to break down. Fish have much less collagen, and it dissolves at a much lower temperature.
This is why fish turns from raw to 'cooked' almost instantly. You aren't melting tough tissue; you are simply setting the delicate proteins. Stop earlier than you think you should.
