In Malaysia the big food myth is that your satay kuah tastes good because its cooked with used sanitary pads (blood and all that other stuff). Sometimes when I go get the kuah myself I stir-stir to see got any "foreign material" in it: so far safe.
i once met this wise old man under a bridge who told me he was 200 years old, and the reason for his long health was that he had been eating pigeons raw.
