Drain the soaked chilies and add them to a blender along with shallots, garlic, ginger, galangal, coriander seeds, and cumin seeds. Blend into a smooth, thick paste. Add a splash of soaking water only if needed.
Cook the spice paste
Heat oil in a heavy-bottomed pot over medium heat. Add the spice paste and cook it slowly, stirring often, until it becomes fragrant and the oil begins to separate. This step takes about 8 to 10 minutes and is essential for depth of flavor.
Add the lamb
Add the lamb pieces to the pot and stir well so every piece is coated in the spice mixture. Cook for 5 minutes, allowing the meat to seal slightly and absorb the spices.
Add coconut milk and aromatics
Pour in the coconut milk, then add lemongrass, kaffir lime leaves, turmeric powder, and salt. Stir gently and bring to a soft simmer.
Slow cook patiently
Reduce the heat to low and cook uncovered. Stir every 10 to 15 minutes to prevent sticking. As the liquid reduces, stir more frequently. This stage takes about 2 hours.
Watch the transformation
The curry will slowly thicken, then darken, and eventually the oil will separate naturally. The sauce will cling to the meat rather than pool in the pot.
Final adjustment
Taste and adjust salt. Continue cooking until the lamb is tender, the sauce is almost dry, and the aroma is deep and roasted.
Rest before serving
Turn off the heat and let the rendang rest for at least 15 minutes. This allows the flavors to settle and deepen.
Notes
Rendang improves with time and tastes even better the next day.
Low heat is crucial. High heat will burn the spices before the meat becomes tender.
If the mixture dries too quickly, reduce heat further and stir more often.
Always use full-fat coconut milk for authentic texture and flavor.
Storage Tips
Refrigerate in an airtight container for up to 4 days.
Freeze for up to 2 months.
Reheat gently on low heat, stirring occasionally.
