Ingredients needed 🛒2 servings
- canned mackerel 1 can
- potato starch 2 tablespoons
- vegetable oil 5 tablespoons
- universal soy sauce 6 tablespoons
- green onion 1/3 bunch (white part only)
- green chili pepper 3 pieces
- whole garlic 5–6 cloves
- sesame oil 1 tablespoon
- toasted sesame seeds a little
Recipe 🍳
- Open the canned mackerel and pour out all the liquid inside, then remove excess moisture.
- Place the mackerel and 2 tablespoons of potato starch into a plastic bag and shake well to evenly coat the fish with a thin layer of starch.
- Heat 5 tablespoons of vegetable oil in a pan over medium-high heat. Once hot, add the starch-coated mackerel and fry until golden and crispy on the outside, then remove and set aside.
- Add 6 tablespoons of universal soy sauce to the same pan.
- Slice the white part of the green onion, cut the green chili peppers into thin strips, and halve the larger whole garlic cloves before adding them to the pan.
- Return the fried mackerel to the pan and reduce heat to low. Simmer for about 1 minute, allowing the vegetables to cook through and the sauce to fully penetrate the crispy starch coating.
- Turn off the heat and drizzle in 1 tablespoon of sesame oil, mixing thoroughly to distribute the aroma.
- Transfer to a serving bowl and sprinkle with toasted sesame seeds to finish.
- Discard the liquid from the canned mackerel and pat dry.
- Place the mackerel and potato starch in a plastic bag and shake to coat evenly. Pan-fry in generous oil until crispy.
- Add universal soy sauce, sliced green onion, chopped green chili peppers, garlic, and the fried mackerel to the pan.
- Simmer on low heat for 1 minute until the sauce is well absorbed, then finish with sesame oil and sesame seeds.
Cooking tips 💡
- Unlike flour, which burns easily under heat, potato starch is heat-resistant and maintains its crisp texture longer without burning.
- Coating the mackerel with potato starch allows the starch to absorb the universal soy sauce completely, preventing the sauce from sitting on top and enhancing deep flavor penetration.
- Adding sesame oil at the end maximizes its rich, nutty aroma in the final dish.
