Preparation

• 在一个大碗里,whik the miso, honey, sesame oil, and soy sauce into a smooth paste. Add the mackerel fillets and toss to coat with the marinade. Marinate for 20 minutes at room temperature. Meanwhile, heat the oven to 350°F.
• Wipe the marinade from the skin side of the fillets. Heat 2 Tbs. of the oil in a 12-inch cast-iron or nonstick skillet over medium-high heat. Working in batches to avoid crowding the pan, cook the fillets skin side down until the skin darkens and crisps slightly, 3 to 4 minutes. As each batch finishes, transfer the fillets skin side down to a lightly oiled baking sheet. Add the remaining 1 Tbs. oil to the skillet between batches if it seems dry. Once all the fillets are seared, put the baking sheet in the oven and bake until the flesh is flaky when poked with a paring knife, 5 minutes. Serve garnished with lemon wedges or slices.
