Vietnamese Caramel, Fish Sauce, and Lake Taupō Chinook Salmon
Vietnamese cooks in the Mekong Delta simmer fish in clay pots over charcoal until the liquid reduces to a thick, savory caramel. The base is built from fish sauce and caramelized palm sugar; black pepper and garlic cut the sweetness. Lake Taupō Chinook salmon carries enough fat to stay moist through the long, gentle reduction. The fillets are seared skin-side down, then braised in the bubbling liquid until the surface glosses and the sauce clings to the flakes. Coconut rice steamed in jasmine rice and thick coconut milk sits beneath the fish. A quick pickle of daikon and carrot in rice vinegar cuts the salt and sugar.
Ingredient List
Prep time: 20 minutes | Cook time: 35 minutes | Serves: 4
The Fish
- 4 Chinook Salmon fillets: Skin on, pin bones removed, approximately 180g each, from Lake Taupō
- ½ teaspoon fine sea salt
- ¼ teaspoon freshly ground black pepper
- 1 tablespoon neutral oil, for searing
The Caramel Sauce
- 60g palm sugar (or soft brown sugar), chopped fine
- 3 tablespoons water (for caramel)
- 60ml fish sauce
- 60ml water (for sauce)
- 4 cloves garlic, finely sliced
- 2 shallots, peeled and sliced into rings
- 1 teaspoon freshly ground black pepper
- 1 long red chilli, sliced (optional)
The Coconut Rice
- 300g jasmine rice, rinsed until water runs clear
- 200ml coconut milk
- 200ml water
- ½ teaspoon fine sea salt
The Quick Pickles
- 200g daikon (white radish), cut into fine batons
- 100g carrot, cut into fine batons
- 3 tablespoons rice vinegar
- 2 tablespoons caster sugar
- 1 teaspoon fine sea salt
To Serve
- ½ cup fresh coriander leaves
- ½ cup fresh Thai basil leaves
- 2 long red chillies, sliced
- 1 lime, cut into wedges
Preparation and Cooking Method
1. Make the Quick Pickles
Toss the daikon and carrot batons with the fine sea salt in a colander. Set aside for 10 minutes so the salt draws out surface moisture. Rinse briefly under cold water and pat dry. Combine the rice vinegar and caster sugar in a bowl until the sugar dissolves. Add the drained vegetables and toss to coat. Set aside at room temperature.
2. Cook the Coconut Rice
Place the rinsed jasmine rice, coconut milk, 200ml water, and ½ teaspoon salt into a heavy pot with a tight lid. Bring to a boil over high heat. Stir once, reduce to the lowest simmer, cover, and cook for 12 minutes. Turn off the heat and leave covered for 10 minutes. Do not lift the lid; steam finishes the grains. Fluff with a fork before serving.
3. Sear the Salmon
Pat the Chinook salmon fillets dry on both sides with paper towels. Season the flesh side with the remaining salt and pepper. Set a wide heavy skillet over medium-high heat for 2 minutes. Add the neutral oil and swirl to coat. Lay the fillets skin-side down. Press each gently with a spatula for 10 seconds so the skin stays flat. Cook undisturbed for 4 minutes. The skin will brown and release when ready; if a fillet sticks, wait another 20 seconds. Flip and cook the flesh side for 60 seconds. Transfer the fillets to a plate.
4. Build the Caramel Base
Add the 3 tablespoons water and palm sugar to the same skillet. Set over medium heat. Let the sugar melt without stirring. Once it bubbles, watch the color. When it reaches a dark amber; about 3 to 4 minutes; remove the pan from the heat. Carefully pour in the fish sauce; it will spit and harden. Stir until the sugar dissolves again. Add the remaining 60ml water, the sliced garlic, shallots, black pepper, and optional chilli. Return the pan to low heat and simmer for 2 minutes so the aromatics soften.
5. Braise the Salmon
Return the seared fillets to the pan, skin-side up. Spoon the bubbling caramel over the tops. Cover and simmer on low heat for 12 to 15 minutes. Every 4 minutes, lift the lid and spoon the liquid over the fish. The sauce will reduce to a thick glaze that clings to the back of a spoon. The thickest part of the salmon should read 52°C on a probe. Remove from heat.
6. Plate
Divide the coconut rice among four bowls. Set one fillet on top of each portion, skin-side up. Spoon the reduced caramel and shallots over the fish. Drain the quick pickles and place a mound beside the salmon. Scatter coriander leaves, Thai basil leaves, and sliced chilli over the top. Serve with lime wedges.
Chef’s Notes for Success
- Caramel color: Stop at dark amber. Black means burnt sugar, which turns bitter and acrid. Pull the pan off the heat as soon as the color deepens; residual heat will carry it further.
- Fish sauce salinity: Vietnamese brands vary in salt content. Taste the finished caramel before returning the fish; if it tastes sharp, add 2 tablespoons water.
- Salmon position: Keep the skin facing up during the braise. Direct contact with the hot pan bottom will overcook the thin tail sections and dissolve the glaze.
- Pickle texture: Salting the vegetables before pickling keeps them crisp. Skipping this step yields soft pickles that lack crunch against the rich fish.
- Pan material: A heavy enamelled cast-iron skillet holds heat steady for the reduction; thin stainless steel may create hot spots that burn the sugar.
- Fillet thickness: Head-end pieces thicker than 3cm need 2 extra minutes in the covered braise. Check the temperature at the thickest point.
- Coconut milk separation: Use full-fat coconut milk. Low-fat versions lack the oil to coat the rice grains, leaving the pile dry.
Lake Taupō Charters
Morning charters on Lake Taupō work the deep southern reaches where Chinook salmon in the 2 to 4kg range hold. Fish of that size yield fillets near 180g that hold up through a long braise without falling apart. We clean and ice your catch on board so the flesh stays firm enough for the caramel. Rods, tackle, and cleaning stations are included.
Book your charter at greatlakefishingtours.club. Bring a cooler so your salmon stays at 4°C or below on the drive to the kitchen. Cold fish takes the sear evenly and keeps its shape through the simmer.
