Step-by-step instructions
1. Make the marinade:
In a bowl, mix together soy sauce, brown sugar, honey, rice vinegar, mirin, gochujang, garlic, ginger, grated pear or apple, and black pepper until smooth.
2. Prepare the fish:
Pat the mackerel dry. Season lightly with salt and pepper. Put the fillets in a shallow dish or zip-top bag and pour the marinade over them. Make sure the fish is coated well. Marinate in the fridge for 30–60 minutes.
3. Cook the onions:
Heat a small skillet over medium heat with a little sesame oil. Add sliced onion and cook until soft and caramelized, about 8 minutes. Set aside.
4. Grill the fish:
Heat a grill pan to medium-high and brush it with sesame oil. Remove the mackerel from the marinade and let the extra drip off. Grill skin-side down for 3–4 minutes until crispy. Flip and grill the other side for 2–3 minutes.
5. Serve:
Place the grilled mackerel on a plate. Top with the cooked onions, sprinkle with sesame seeds, and add green onions or chili slices if you like.
Serve hot with steamed rice and your favorite side dishes.
