An approachable take on a classic Cantonese steamed fish preparation that swaps the traditional whole fish for mild white fillets that are cooked gently in the vapors of a bamboo steamer alongside fragrant ginger until moist and just falling apart, coated in a sweet and salty sauce, topped with spring onions and a drizzle of sizzling hot oil. Serve with rice and a salad or a simply cooked green vegetable for a quick and simple weeknight meal.
