Heat desiccated coconut in a heavy-based
frying pan and stir constantly until it is evenly browned. It
should be a fairly deep brown, but be careful not to burn it.
Spread coconut on a large plate to cool. Combine all ingredients
in an electric blender, cover and blend on high speed to a smooth
paste. (It may be necessary to add a little more chopped onion
or lemon juice if there is not sufficient liquid.) Shape into a
round flat cake and mark the top in a criss-cross pattern with a fork
or the back of a knife. Serve with rice and curry.
