Cod cakes are a delicious and innovative way to enjoy this versatile fish. To make the cakes, combine cooked cod with mashed potatoes, breadcrumbs, and herbs, then form into patties and fry until golden brown. Serve the cod cakes with a zesty lemon aioli, made by combining mayonnaise, lemon juice, and garlic. The combination of crispy cod cakes and tangy aioli creates a delicious and satisfying meal.
