Some fish sauces rank more than others. We don't have Red Boat in my country but I did come across some generic supermarket brands that aren't too smelly. Fish sauce is my "secret-sauce" when cooking spaghetti bolognese, I use it as an alternative to salt. Not so secret anymore huh! Sometimes our supermarket runs out of their generic re-bottled brand, so I have to go to the asian section. The Thai ones have a sweetness to them, more so than normal - but boy do they stink! But once it's cooked well into the mix (add it in early rather than later), there's no trace left of the smell. What's left is this beautiful flavour that brings out the goodness of meat to a whole new level. .
