I'm talking about fish sauce.
I find it to be revolting in smell, yet wonderful in taste. There's nothing that compliments a thai curry better than a drizzle of fish sauce over the top. As a matter of fact, it's what I'm eating right now. It's salty and pungent, yet mellow at the same time. Not only that, but somehow it manages to compliment and enhance the flavors of everything else in the dish.
Amazing how something that smells so awful can taste so very good.
Kind of like aged cheese.
What other foods or food items smell awful but taste wonderful?
