‘Pick it up with your fingers and place it, tip first, into your mouth, and lick its surface with your own...In the act of French kissing, where the tongue of another finds its way into one’s own mouth, is the only time when we experience the sensation of two tongues in our mouth. Except for now!’  
 
The principle organ of taste, the tongue is the gatekeeper to the body. It frequently traverses the threshold of the mouth, past the teeth and lips, to taste and judge the world beyond. ‘O ambivalent organ’ as Erasmus called it in 1525, is actually anything but equivocal when we experience the taste of a food which we do not like.
