Whitebait is a bit of a delicacy in New Zealand, and whitebait from the West Coast of the South Island is the best. The idea is to have more whitebait than batter, however it you go to a restaurant you will probably find that it's the other way round!
West Coasters also serve them with mint sauce which is very tasty. Another thing to do is heat the oven to 50degrees C, and butter 4 slices of white bread. Put these on a plate in the oven (butter side up) and as each whitebait pattie is cooked put them on the bread. Us kids used to fight over the bread at the end as it tastes yummy(strange but true).
