Finely chop the lemongrass, onion, garlic, and chilis. Add the coriander, cumin, anise, black pepper, and water, then grind down into a smooth paste.
Beef Curry
Heat a pot over low heat and add the Rendang curry paste. Slowly cook for 10 minutes.
Turn the heat up to medium then add the diced beef. Cook and stir until browned on all sides, about 2 minutes.
Add the coconut cream and enough water to just cover all the meat. Cover with a lid and bring to a boil. Add the sugar and kaffir lime leaf then reduce the temperature and simmer. Stir regularly and add additional water if the level falls beneath the meat.
The meat is cooked when it is very tender, about 35 minutes. Remove the lid and let the sauce reduce down to thicken and cover the meat.
