Crispy Aji (Horse Mackerel) with Zesty Ethnic Sauce: A Taste of Southeast Asia

【Recipe】Crispy Horse Mackerel with Ethnic Sauce | A Blissful Dish Infused with Nam Pla and Cilantro

The true essence of Southeast Asian cuisine lies in the complex, deep interplay of “sour, sweet, and salty” flavors. Today, I’m excited to share a dish featuring crispy fried horse mackerel (Aji) topped with a generous serving of my special Nam Pla-based ethnic sauce.

To be honest, when I first encountered Nam Pla (fish sauce) and cilantro, I was so surprised by their unique aromas that I kept my distance for a while. However, a bowl of Pho at a Vietnamese restaurant with a friend completely opened my eyes! Now, I am absolutely captivated by their fragrance and fresh taste.

Ingredients (Serves 4); Crispy Aji (Horse Mackerel) with Zesty Ethnic Sauce

• Horse Mackerel (Aji), cleaned: 240g
• Cooking Flour (Granulated cake flour): 12g
• Frying Oil: As needed
• Red Onion: 80g
• Cilantro (Coriander/Silantro): 20g
• Lime: To taste

【☆ Special Ethnic Sauce】

• Nam Pla (Fish Sauce): 8g
• Dark Soy Sauce: 8g
• Oyster Sauce: 8g
• Doubanjiang (Chili Bean Paste): 2g
• Sugar: 2g
• Water: 40g

💡 Point: The Secret of Cooking Flour Using a free-flowing “cooking flour” (specially processed cake flour) allows for a thin, even coat without clumping. This ensures a surprisingly crispy finish even with a small amount of oil, preventing the fish from becoming greasy!

Crispy Aji (Horse Mackerel) with Zesty Ethnic Sauce Cooking Instructions

1. Prep the Fish: Thoroughly wipe away any moisture from the surface of the horse mackerel with paper towels. (This is the secret to removing odors and achieving maximum crispiness!) Lightly dust the surface with cooking flour.
2. Fry until Crispy: Heat oil in a frying pan and begin frying the fish. Placing the fish “skin-side down” first prevents the heat from curling the flesh, ensuring a beautiful presentation. Fry until the surface is golden brown and crispy.
3. Make the Sauce: Combine all the ingredients for the 【☆ Sauce】 in a small saucepan and bring to a heat. Once it reaches a boil, remove from heat immediately to preserve the fresh aroma.
4. The Finishes: Thinly slice the red onion. Wash the cilantro, pat dry, and cut into bite-sized lengths.
5. Plating: Arrange the fried fish on a plate and garnish with the red onion and cilantro. Pour the warm sauce generously over the top, and finish with a fresh squeeze of lime.

Culinary Trivia for Success

• Names for Cilantro: It is known as “Phak Chi” in Thai, “Coriander” or “Cilantro” in English-speaking countries, and “Xiang Cai” in Chinese. Technically, “Phak Chi” refers to the fresh leaves, while “Coriander” often refers to the dried leaves and seeds.
• Nam Pla (น้ำปลา): In Thai, “Nam” means liquid and “Pla” means fish. It is a powerhouse of umami made from salt-fermented fish. If you love this aroma, be sure to check out my previously shared Gapao Rice recipe! 👉　Gapao rice（Thai Basil Stir-Fry ）
