500g of crabmeat makes about 10 medium-sized patties.  I found this recipe from the Anglesea Grill that used to be on Ponsonby Road for quite a number of years - this is Dean Bett's (Chef/owner) receipe :

WAIKANAE CRAB CAKES:

3 eggs, lightly beaten, 1tspn white pepper, 1 tblspn of Colman's Hot Mustard, 1 tblspn fresh garlic puree, 500g crabmeat - flaked or minced, 1 cup dried breadcrumbs, oil for frying, 4 heaped tblspns aioli, 4 lemon wedges & 2 tblspns chopped parsley

Mix together the eggs, pepper, mustard and garlic.  Add the crabmeat then stir gently to blend.  Form mixture into patties and coat with breadcrumbs.  To cook - heat the oil in a frying pan and fry in batches.  Flatten gently and cook, until brown and crisp.  Serve garnished with aioli, lemon and a sprinkle of chopped parsley.  Makes about 10.
