When ready to cook, pour vegetable oil into a large, heavy skillet to a depth of 1/4". Heat the oil over medium-high heat. When it is hot, but not smoking, add the crab cakes and cook until golden on both sides, turning only once, about 4 minutes per side. If you are cooking the crab cakes in batches, transfer them to a platter in a warm oven. Serve hot with lemon wedges on the side. 470 calories/serving; GL=2, Glycals=10
