Trung Kho (Vietnamese Braised Eggs)

Thit kho trung - pork belly and eggs braised in coconut water and caramel until the eggs go amber and the pork falls apart. The Tet dish: made in a big pot before the new year and eaten for days, which is exactly the point of it. The caramel (nuoc mau) is the soul of the thing and it is made by taking sugar past where your nerve says stop.

Ingredients

• 8 eggs, hard-boiled and peeled
• 1 kg pork belly, skin on, cut into 4 cm cubes
• Nuoc mau (caramel sauce)
• 100 g sugar
• 3 tbsp water
• 3 tbsp hot water (for stopping the caramel)
• The braise
• 1 litre fresh young coconut water (NOT sweetened coconut drink, and not coconut milk)
• 4 tbsp fish sauce
• 3 shallots, sliced
• 3 cloves garlic, minced
• 1 tsp black pepper
• 1 tbsp sugar, to taste
• 2 red chilies (optional)

Directions

Key ingredients

Black Pepper · Fish Sauce

1. Blanch the pork. Cover the cubes with cold water, bring to a boil, boil 3 minutes, then drain and rinse well. This is not optional - it’s what keeps the braise clean rather than scummy.
2. Marinate. Toss the pork with the shallots, garlic, 2 tbsp of the fish sauce, the pepper and 1 tbsp sugar. Leave 30 minutes.
3. Make the nuoc mau. In a heavy pot, combine the sugar and 3 tbsp water. Cook over medium heat WITHOUT stirring until it turns a deep amber - darker than you want to; it should be the colour of strong tea and just starting to smoke. Underdone caramel makes a sweet braise instead of a savoury one.
4. ⚠ Kill the caramel with HOT water, 3 tbsp, standing back. Cold water in molten caramel spatters violently. It will seize and hiss; keep the heat low and stir until it’s a smooth dark syrup.
5. Add the pork and its marinade to the caramel and sear briefly, turning to coat.
6. Add the coconut water and the remaining fish sauce. Bring to a boil, skim, then reduce to a bare simmer, cover, and cook 1 hour until the pork is tender and the skin is translucent.
7. Add the peeled eggs and chilies. Simmer uncovered another 20-30 minutes, so the eggs take on colour and the sauce reduces and glosses.
8. Rest it. Like most braises it’s better the next day. Serve with rice and pickled bean sprouts.

Notes

Coconut water, not coconut milk

This catches people constantly. It’s fresh young coconut WATER - the thin clear liquid. Not coconut milk, not sweetened coconut drink from a carton. The coconut water is what gives the braise its particular rounded sweetness and helps tenderise the pork.

The Tet association

This is a new-year dish, made in a large pot and eaten over several days of the holiday - a keeping braise, in a hot country, before refrigeration was a given. That’s why the pot is enormous and why the eggs are in it: the eggs are cheap volume that soaks up an expensive sauce. (Same logic as Chinese lu dan - see Lu Dan (Master Stock Eggs).)

Where the flavour is

Remember that the eggs have been in that sauce for 30 minutes, not 30 days. The colour is a rim, and the middle is a plain boiled egg. That contrast is the design, not a shortfall.

This is a BRAISE, not a marinade

Worth noting because it changes the safety picture entirely: the egg cooks IN the sauce for minutes at high temperature. It is not a low-acid room-temperature steep. None of the pickled-egg hazards apply here.
