How to Make It
In a large bowl, cover the beans in cold water by 2 inches and let stand overnight at room temperature. Drain.
Cover the shrimp with cold water and soak 30 minutes. Drain.
In a food processor, pulse the beans, shrimp, onion, garlic, 1 teaspoon of salt and 1/2 teaspoon of pepper in batches until finely ground.
Line a baking sheet with paper towels. In a large pot, heat the oil to 375°. Make football-shape fritters with the batter by squeezing about 1/4 cup of the batter in your palm. Fry the fritters in batches until dark golden brown, about 6 minutes per batch. Transfer the acaraje to the paper towel-lined baking sheet to drain, then serve.
