Before frying, the fish is scored at microscopic intervals all along both sides in order to break up some of the many bones, tenderize the flesh, and help it cook faster. After a quick dusting in highly seasoned corn meal, it goes into the fryer where it crisps up within minutes. Served with the highly acidic orange-fleshed limes of the region, it’s moist, juicy, well-balanced, and perfectly satisfying, with none of the muddy flavors that farm-raised freshwater fish can carry.
Even more impressive is the hospitality shown to us. We were there mid-week during the off-season, when most restaurants and hotels are closed. The small, family-owned fried fish shop we stopped at was opened by the father-and-two-kids team just for our benefit. We ate fried fish while they sat next to us eating their own tasty looking lunch of stewed beef rib soup. The simplest aji I know is as easy and delicious as it gets: chop up an onion, some hot peppers, and cilantro, top up with water, and season with salt aggressively. Try it. Seriously.
