Heat the wok with medium fire. Add coconut milk, spice mixture, bay leaf, kaffir lime leaf, galangal, lemongrass and salt. Mix it well. Put beef chunks after the sauce is boiled.

Slow cook beef with low heat. Simmer it for approximately 4 hours until coconut milk turn into oil and the beef becomes dark brown and tender. Keep stir the beef every 10 minutes while simmering it, so it won't burnt.

Some say the more you reheat the beef on the next day, the more tasty it gets.
