Dried noodles in a pot with a sachet of soy sauce, launched in Britain in 1979 and never off a student shelf since.
The chicken and mushroom flavour is the default and the argument about the best one has never been settled. The sachet always burst wrong.
It was cheap, it was hot, and it required nothing but a kettle, which at certain points in life is the entire specification.
