Crunchy Salmon Croquettes

Pour salmon juice into a small bowl or measuring cup. Place salmon in a mixing bowl; clean off skin and bones.

Use your fingers or a fork to flake the salmon. Add egg and mix well; add flour and stir to combine. Add onion, bell pepper, and black pepper. Mix well.

Add baking powder to the salmon juice; beat with a fork until foamy. Pour into the salmon mixture and fold together. Form into thumb-sized croquettes.

Heat oil in a large skillet over medium heat. Cook croquettes in batches until golden brown, about 5 minutes per batch.
