Marinating mackerel in soy sauce is a fantastic way to infuse the fish with flavor. The soy sauce adds a savory and slightly sweet taste to the rich and oily mackerel, making it even more delicious. Grill or pan-fry the marinated mackerel until it is cooked through and crispy. Serve with a side of steamed greens and a squeeze of lemon juice for a delightful meal.
