--------  ------------  --------------------------------
     1/2  kilogram      red tomatoes
   1      teaspoon      turmeric -- ground
   8                    peppercorns
   3                    cloves
     1/2  teaspoon      cumin
     1/2  kilogram      fresh uncooked prawns -- cleaned and shelled
   1                    coconut
   2      large         onions -- finely sliced
   1      1" piece      ginger -- finely sliced
   4      cloves        garlic -- finely sliced
   2                    green chiles -- finely sliced

Preparation:

Skin and chop the tomatoes then pass through a sieve to remove seeds. Grind together the turmeric, peppercorns, cloves and cumin. Extract a thick and thin milk from the coconut. Fry the onion, ginger, garlic and chiles in a little oil until onions are slightly brown. Add spice mix and fry for 30 second or so. Add the prawns (if using cooked prawns add at the end of the cooking) and fry for a few minutes. Add the tomato juice and cook for 5 minutes. Add the thin coconut milk and cook for 5 minutes. Add the thick coconut milk and cook until the sauce is thick. Serve with rice. Note : I was told this may be served with roasted dried prawns, never got to try them though.
