Has anyone ever notice, or maybe it's just me, that red maggots never seem to be as large in size as the other colours? And yet I like using reds.
Turmeric and corriander powder are both great flavour enhancers, but it's also because they are great de-greasers too. Gets all that amonia laden sweat off them and I don't think fish like that so much.
And of course, aniseed oil.
