I try and limit our son's simple carbs. Making fish cakes .. for that matter most 'pan' cakes I just add shredded veggies, seasonings and a few eggs to make a batter to pan fry.
Tonight I took two small cans of Alaskan salmon, drained and flaked .. beat in three eggs, 1/4 cup diced celery, 1/4 cup diced onion .. salt/pepper and a little dill weed.
Spooned them into a large hot skillet with a little chicken fat. Turned once .. and served with a homemade tarter sauce made from homemade mayo, lemon juice and diced fermented dill pickles.
These cakes were gone in a quick minute.
