Braised Fish (Cá Kho): Traditional Vietnamese Comfort Food
(Written by Duncan Dress)
At Viet Kitchen, we present you with the timeless recipe of Braised Fish (Cá Kho), a dish known for its rich, savory flavors and tender, caramelized texture. Traditionally slow-cooked in an earthenware pot, the dish combines fish sauce, coconut water, and caramelized sugar to create a balance of sweet, salty, and umami notes. A staple in Vietnamese households, Cá Kho is best enjoyed with steamed rice, pickled vegetables, and fresh herbs.
The Essence of Braised Fish
At the heart of this dish is the caramelization process, which imparts a slightly sweet, nutty aroma that balances perfectly with the savory, umami-rich fish sauce. The use of coconut water adds a subtle sweetness, enhancing the dish without overpowering the natural flavors of the fish. Traditionally, snakehead fish (cá lóc) is used, but catfish or other firm white fish can be substituted for similar results.
How to Make Braised Fish (Cá Kho)
Ingredients (Serves 4):
- Fresh Fish (snakehead or firm white fish): 500g, cut into medium pieces
- Fish sauce: 3 tablespoons
- Caramelized sugar: 2 tablespoons (or use coconut caramel for a deeper flavor)
- Coconut water: 1 cup
- Garlic: 3 cloves, minced
- Shallots: 2, finely chopped
- Black pepper: 1 teaspoon (cracked for stronger flavor)
- Fresh chili: 1, sliced (optional for heat)
- Green onions & coriander: For garnish
Instructions:
- Caramelize the Sugar: In an earthenware pot or a deep pan, gently heat sugar over medium heat until it melts into a golden brown caramel. Be careful not to burn it. Add a splash of hot water to loosen the caramel.
- Prepare the Fish: While the caramel is simmering, marinate the fish pieces with fish sauce and cracked black pepper for at least 15 minutes. This will infuse the fish with a savory base before cooking.
- Simmer the Fish: Add garlic and shallots to the caramel and sauté until fragrant. Gently place the fish into the pot, skin side down. Pour in the coconut water until the fish is just covered. Add chili for extra spice (optional). Reduce the heat and let the pot simmer on low for 45 minutes, allowing the sauce to thicken and the fish to absorb all the flavors.
- Final Touches: Towards the end of the cooking time, let the sauce reduce until it coats the fish with a shiny, caramelized glaze. Turn off the heat and let the fish rest in the sauce for a few minutes before serving.
- Garnish and Serve: Serve the braised fish with steamed rice, garnished with fresh green onions and coriander for brightness. You can also add a side of pickled vegetables for a contrasting bite.
FAQs about Braised Fish (Cá Kho)
- How do I prevent the fish from burning while braising?
Use low heat and stir the pot occasionally to prevent the caramel from sticking or burning. If you notice burning, quickly transfer the fish to another pot and add a bit more water or coconut water to dilute the burnt taste. - What can I do if the dish turns out too salty?
Add a little more coconut water or fresh water to balance out the flavors. You can also add a bit of sugar to mellow the saltiness. - How can I fix burnt braised fish?
If the fish burns slightly, remove the burnt bits carefully. Transfer the remaining fish to a new pot, add fresh sauce (fish sauce, water, sugar), and continue braising at a lower temperature. - What makes coconut water important in this recipe?
Coconut water provides natural sweetness that balances the salty fish sauce, creating a harmonious flavor. If coconut water is unavailable, you can use water and a teaspoon of sugar.
Tips for the Best Braised Fish
- Use Fresh Ingredients: Fresh fish and herbs enhance the flavors and elevate the dish.
- Caramelize Sugar Carefully: The caramelization process is crucial for deep flavor, so take your time and avoid burning it.
- Cook Slowly: Simmering the fish over low heat allows the flavors to meld and the sauce to thicken without rushing the process.
- Garnish for Brightness: Fresh herbs like coriander and green onions add color and a refreshing contrast to the rich, savory fish.
