Beer-Battered Fish Tacos for When the Catch Is Small but the Crew Is Hungry

Not every fish you catch is a trophy. Sometimes you land a couple of small mackerel, a scrawny bass, or a bag of fillets that look more like snacks than dinner. This is not a problem. This is an opportunity, because small, thin fillets are exactly what you want for fish tacos. They cook in under two minutes, they take a batter beautifully, and they turn a modest catch into a meal that feels like a celebration rather than a compromise.

The batter is the easy part. Equal parts flour and cold beer, whisked together until it is the consistency of thin pancake batter. The beer does two jobs: the carbonation makes the crust light and crisp, and the alcohol evaporates quickly, which helps the batter set before it soaks up too much oil. Any beer works, though I would steer away from anything too dark or too hoppy. A basic lager or a pale ale is perfect. If you do not drink alcohol aboard, a very cold sparkling water with a pinch of baking powder gets you most of the way there.

Frying on a Boat Without Setting It on Fire

Deep frying on a sailboat makes some people nervous, and reasonably so. The good news is you do not need to deep fry. A shallow fry in a cast-iron skillet with an inch of oil is enough, and it is far safer because there is less hot liquid to slosh. Heat the oil to about 350 degrees Fahrenheit, or until a drop of batter sizzles the moment it hits. If you do not have a thermometer, drop in a small piece of bread. If it browns in about a minute, you are ready.

Pat your fish fillets very dry, season them lightly, and cut them into strips about the length of your thumb. Dip each strip in the batter, let the excess drip off, and lay it gently into the oil away from you. Do not crowd the pan. Three or four pieces at a time is plenty. Flip once after about ninety seconds and cook until deep golden. Lift them out onto a rack or a plate lined with paper. If the boat is rolling, keep one hand on the pan handle at all times and never leave the stove unattended.

While the fish fries, warm your tortillas. On a boat, the easiest way is directly over a low flame on the burner, a few seconds per side, until they puff slightly and smell toasty. Stack them in a clean towel to stay warm. Then set out the toppings: shredded cabbage tossed with lime juice and a pinch of salt, a bowl of crema or thinned sour cream, sliced radishes, cilantro, and plenty of lime wedges. If you have a jar of pickled onions in the locker, now is the moment.

Building the Taco and Cleaning Up

Assemble each taco with a piece or two of fish, a pile of cabbage, a drizzle of crema, and a hard squeeze of lime. Eat them standing up if you have to. They are messy, and that is part of the charm.

The cleanup is the only real downside of frying at sea. Let the oil cool completely before you touch it, then strain it into a jar if it is still reasonably clean and save it for the next fry. Wipe the skillet with paper towels before washing, and never pour oil over the side. A little care here keeps the anchorage clean and your conscience clear. Small fish, cold beer, hot oil, and a lime. That is a good day on the water by any measure.
