After measuring all ingredients on a gram scale, fold the crab meat and canola oil into the egg whites. Melt the butter in a nonstick frying pan. Make 3–4 crab cakes in the pan and fry them similar to a pancake. When the edges are slightly browned and cooked, flip them over to cook the other side. Cook them until they are cooked thoroughly and move them to a serving plate. Scrape all of the fat out of the pan onto the crab cakes. Mix the mayonnaise and the relish together and serve as a dipping sauce. Serve the celery on the side.
Notes: If an all-in-one style meal is desired, simply chop the celery very fine and mix all of the ingredients together. Cook by the same method and serve.
Add a pinch of seafood seasoning, such as Old Bay, to add a bit of extra flavor to the crab cakes.
If your ratio allows, swap out the tartar sauce for “cocktail” sauce by mixing horseradish with low-sugar ketchup.
