Method:
Heat 1 tablespoon of the oil in a large skillet. Add celery, corn, green onions, bell peppers, salt and pepper and cook, stirring occasionally, until tender, 8 to 10 minutes. Transfer to a large bowl and set aside to let cool. Once cooled, add 6 tablespoons of the breadcrumbs, crab, egg and zest and mix well.
Transfer remaining breadcrumbs to a wide, shallow dish. Form crab mixture into eight 3-inch wide patties, packing each together with your hands. Gently roll each patty in the breadcrumbs to coat all over then transfer to a large plate. Cover and refrigerate until chilled, about 30 minutes. Mix mayonnaise and chile sauce together in a bowl then cover and refrigerate.
Heat a large, deep skillet over medium-high heat. Pour in enough oil to reach a depth of about 1/3 inch and heat until oil starts to shimmer. Carefully add crab cakes (working in batches, if needed) and cook, gently flipping once, until cooked through and deep golden brown, 6 to 8 minutes total. Transfer to a paper towel-lined plate as done and season with salt and pepper. Serve crab cakes with spicy mayo on the side.
