It’s not everyday that you get the chance to try a fish you’ve never even heard of before. Last week I cooked paiche (pie-chay) a fish from the Amazon, also known as arapaima or pirarucu. Freshwater paiche are huge, growing be up to near 500 pounds, and breathe through lungs rather than gills. Considered a prehistoric fish, the flesh is very firm, but also rich and high in omega-3 fatty acids.
Endangered in the wild from overfishing, paiche is now raised commercially in ponds so wild fish remain protected, and free of any antibiotics or mercury. It’s one of the top fish farmed in Peru, and you may find it on restaurant menus or at Whole Foods, the only retailer currently selling it in the US.
It’s easy to cook paiche for a couple of reasons, because it’s dense and firm it won’t easily fall apart and because it’s rich it doesn’t get dry, even if you overcook it. It has a very clean, buttery slightly sweet flavor and is somewhat similar to sea bass or cod in texture.
