Sprinkle the salt, garlic salt, black pepper, red chile flakes, crab boil seasoning, chopped celery, and chopped onions. Using your hands, combine all the ingredients together into a homogenized mixture. Set aside so the flavors blend.
In another large bowl, combine the bread crumbs, crab meat, and crab sauce.
Mix into a homogenous blend.
Take a small handful of the bread mixture and using your thumb or finger, press out a hole. Take a small scoop, about 1 1/2 ounces, of the crab mixture and place it into the hole. Bring the bread mixture around the crab mixture, forming a patty. Set aside on a sheet pan lined with parchment paper, or a large platter. Continue making patties until all of the mixtures are used.
In a large skillet, pour 1 1/2 inches of oil into the pan.
Heat the oil to 375 degrees F., or until a small piece of the bread mixture sizzles and bubbles when placed in the oil.
Place patties in the pan, being careful not to crowd them. Fry until golden on 1 side, about 3 to 4 minutes, and then flip over and fry until golden on the other side.
