How do you use Tim Tams?
Pair up a Tim Tam with your favourite hot drink, nibble off the corners, then use the biscuit as a straw to suck up a little of the drink until the Tim Tam is about to collapse. Quickly eat it all up before it collapses into a puddle in your fingers.
Do Tim Tams melt?
Opposite corners of the Tim Tam are bitten off, one end is submerged in the beverage, and the beverage is sucked through the biscuit as though the Tim Tam itself were a straw. The crisp interior biscuit is eventually softened and the outer chocolate coating begins to melt, at which point the biscuit is eaten.
