Vietnamese Caramelized Fish Holiday Plate (Ca Kho To)

About This Recipe

Ca kho to, caramelized fish braised in a clay pot, is one of Vietnam's most cherished home dishes, especially common at family gatherings and holiday tables in the Mekong Delta region. Fish, traditionally catfish, is braised in a homemade caramel sauce along with fish sauce, black pepper, and a touch of pork fat, producing a dish that's intensely savory-sweet with a glossy, deeply colored sauce. The technique mirrors thit kho's caramel-based braising method, but the fish cooks much faster than pork belly, so the caramel and braising liquid are prepared first and the fish added only in the final stage to prevent it from falling apart or overcooking. A traditional clay pot (to) helps retain heat evenly, though a heavy skillet works nearly as well at home. Served as part of a full holiday plate alongside rice and quick-pickled vegetables for freshness and crunch, this dish represents the kind of humble, deeply flavorful cooking that anchors Vietnamese family celebrations, valued far more for its taste than for elaborate presentation.

• 700 gcatfish or firm white fish(cut into steaks)

Instructions

1. 1

   Make the caramel

   In a clay pot or heavy pot, combine sugar and water. Cook over medium heat without stirring until deep amber, about 6-8 minutes.

2. 2

   Build the braising liquid

   Carefully add fish sauce and coconut water to the caramel (it will bubble). Stir in garlic, shallot, and black pepper.

3. 3

   Simmer the base

   Bring to a simmer and cook 3-4 minutes until slightly reduced.

4. 4

   Add the fish

   Carefully lower the fish steaks into the sauce. Spoon sauce over the top to coat.

5. 5

   Braise gently

   Cover and simmer on low heat 20-25 minutes, spooning sauce over the fish occasionally, until it's cooked through and the sauce has thickened and turned glossy.

6. 6

   Finish

   Scatter sliced red chile over the top in the last 2 minutes.

7. 7

   Plate and serve

   Serve the fish directly from the pot alongside rice and pickled carrot and daikon, garnished with scallions.

Variations

• •

  Use salmon or another firm fish steak if catfish isn't available locally.

• •

  Add a few slices of pork belly to the braise for extra richness, a common Southern Vietnamese variation.

• •

  Adjust the chile to taste, or omit it entirely for a milder, more traditional version.

Storage

Refrigerate up to 3 days in an airtight container, fish submerged in its sauce. Reheat gently on low heat to avoid breaking the fish apart further; the sauce actually deepens in flavor by the next day.
