#2: Marmite.

Students frequently proffer gifts of food and drink, presumably because most English as a Foreign Language teachers look as if they are on the verge of expiring from a lack of sustenance or booze. Among the many disgusting interesting British culinary delicacies my learners come across in their sojourns is Marmite. 

Mmmm.

I have known many to purchase it in the mistaken belief that Marmite is somehow related to marmalade, and is therefore sweet.

They are rapidly disabused of this notion the minute they ingest a large spoonful.

Fortunately, I love the stuff, and generally waste no time letting my tutees know this. As a result, I have been the recipient of several Marmite-related gifts, some of which haven't even been opened, over the last few years.
