Great to taste and easy to make. Had this before when I lived in Darwin prepared by Thursday Island boys. They caught fish and put it straight in to the mix. This is a great recipe that everyone likes. Good for a party.
This is a wonderful recipe, but it needs a warning: 5T of ginger and 5 cloves of garlic is intense for people who aren't prepared for it. And what in the world is "nummus"? It must be one of the rarest words in the world. Googe says it's a kind of Roman coin, and then the third Google entry is... this recipe!
