Grind all the spice paste ingredients into a paste.
Heat the oil to high heat and fry the spices, and then lower the heat and fry the sliced onions and julienne ginger.
Add the spice paste and fry until the oil turns orange in color.
Add the beef, coconut and coconut milk and cook until beef is tender. I use the pressure cooker, and that takes 30 minutes. Without the pressure pot, it takes 4 hours.
If using the pressure cooker, open the pot and evaporate the liquid.
Serve with rice.
