Instructions
Defrost Pork Skin
Place the frozen shredded pork skin in the refrigerator or under cold running water until fully thawed.
Time: PT30M
Boil Water with Ginger
In a pot, combine 1 L water and 30 g peeled ginger slices. Bring to a rolling boil over high heat.
Time: PT5M
Temperature: 100°C
Add White Wine
Add 50 ml dry white wine to the boiling ginger water and let it return to a boil.
Time: PT2M
Temperature: 100°C
Blanch Pork Skin
Add the thawed shredded pork skin to the boiling liquid. Boil quickly for about 1 minute while stirring to loosen the strands.
Time: PT1M
Temperature: 100°C
Rinse and Cut Skin
Drain the skin in a sieve, rinse under cold running water until clear, then pat dry. Use scissors or a knife to cut the strands into small bite‑size pieces to prevent clumping.
Time: PT5M
Prepare Sugar‑Salt Solution
In a bowl, dissolve 150 g sugar and 6 g salt in 150 ml boiling water (or room‑temperature water) until fully dissolved.
Time: PT5M
Slice Ham into Threads
Take the 500 g pre‑sliced ham, cut each slice in half, then slice into thin threads (similar to shredded meat).
Time: PT10M
Marinate Ham and Skin in Vinegar
In a large bowl combine the 250 ml red wine vinegar, the sugar‑salt solution, 1 ml food red coloring, then add the ham threads and the boiled pork skin. Cover tightly with plastic wrap and let sit at room temperature for 3 hours (or overnight in the fridge).
Time: PT3H
Drain Marinated Mixture
After soaking, pour the mixture into a sieve and let excess vinegar drain completely.
Time: PT5M
Stir‑Fry Garlic
Heat 2 tbsp cooking oil in a pan over medium‑high heat. Add 10 g minced garlic and sauté until fragrant, about 2 minutes.
Time: PT2M
Temperature: medium‑high
Add Boiled Skin
Add the drained pork skin to the pan and stir‑fry for another 2 minutes so the skin absorbs the oil and garlic flavor.
Time: PT2M
Temperature: medium‑high
Season with Fish Sauce
Pour in 40 g fish sauce, stir evenly and cook for 1 minute on medium heat.
Time: PT1M
Temperature: medium
Simmer with Water
Add 150 ml water, bring to a gentle simmer and cook for 5‑7 minutes (≈6 minutes) until the skin becomes soft and the liquid reduces.
Time: PT6M
Temperature: medium (≈90°C)
Add Red Coloring (Optional)
Stir in a few more drops of food red coloring if a brighter hue is desired.
Time: PT1M
Prepare Ham Seasoning
In a bowl combine 8 g roasted rice powder, 5 g minced fresh chili (seeds removed), 20 g minced garlic, and 10 g crushed whole peppercorns. Mix well.
Time: PT5M
Combine Ham with Cooked Skin
Add the cooked pork skin to the seasoned ham mixture. Using gloves, mix thoroughly so the skin sticks to the ham threads.
Time: PT2M
Bag and Remove Air Bubbles
Transfer the combined mixture into a sealable plastic bag or tray. Flatten, then gently beat the bag to expel air bubbles. Fold the bag, turn it upside‑down, and flatten again.
Time: PT5M
Press and Chill to Firm
Place a heavy board or weight on top of the bag/tray and refrigerate for 8 hours (or 4‑8 hours) until the fermented pork becomes firm.
Time: PT8H
Slice and Serve Cold
Remove the firm block from the bag, slice into desired thickness, and serve cold. Optionally wrap each slice with a piece of garlic, chili and a laksa leaf for presentation.
Time: PT5M

Chef Tips from the Video
- Use a high‑quality red wine vinegar for a cleaner flavor
- A pinch of sugar in the final stir‑fry balances the acidity
- For a brighter color, add food red coloring after the skin has softened, not before.
Troubleshooting
Pork skin remains tough after cooking
Extend the simmering time by 2‑3 minutes and add a splash more water; ensure the skin was fully boiled initially.
Fermented pork is too salty
Rinse the ham and skin briefly before the final mixing, or reduce the amount of fish sauce next time.
Mixture does not firm up after chilling
Make sure the bag is tightly sealed and a sufficient weight is applied; increase chilling time to 10‑12 hours.
