What Is the Tim Tam Slam?
The Tim Tam Slam is an Australian tradition that has helped make these cookies famous worldwide.
To properly execute a Tim Tam Slam, follow these steps:
- Prepare a Hot Beverage: Brew a hot cup of coffee, black tea, or hot cocoa.
- Bite the Corners: Bite off a small piece from two opposite diagonal corners of the rectangular cookie to expose the inner wafer layers.
- Use it Like a Straw: Submerge one bitten corner into your hot drink and suck the liquid up through the opposite end.
- The Slam: The hot liquid will rapidly melt the interior cocoa cream and soften the inner biscuits. The moment you feel the liquid hit your mouth, pop the entire warm, gooey cookie into your mouth before it structurally collapses.
