I never leave Australia without stashing boxes of Tim Tams away in my suitcase—that'd be one for the family, one for a friend, and three for me. These chocolate-coated biscuit sandwiches—two porous chocolate cookies with cream in the middle—come in delightful, unexpected flavors like mint, honeycomb, and rum-raisin. They're so crisp and airy, it's shockingly easy to scarf them down. For the authentic Aussie experience, try a Tim Tam Slam: bite off opposing corners and dip one end in a cup of tea, then suck the liquid up through the biscuit like a straw. Say what you will, but it sure beats Twizzlers and Coke.
