There is an art to vegemite. Less is best. I still
remember the horrified looks my family gave as a friend
from England smeared a full half a tablespoon or more on
her toast and bit in. She probably remembers that
moment really well too !

Vegemite should not be mistaken for jam.
Put vegemite on a sandwich the way
you would marmalade, and you might be sick.

You should use about a, um, 'smear' - or very small bit of
vegemite. The toast should be seen underneath.

And vegemite is eaten with butter or marg. Not on just
plain bread. The more butter you use, the more
vegemite, so a vegemite roll can have almost half a
teaspoon of vegemite, if it also has a teaspoonful of
butter.
