America, you're about to discover your favourite new biscuit.

Australia's much-loved Tim Tam biscuit is now available widely in the U.S., following years of sporadic imports bought up by homesick expats and curious Americans.

A Tim Tam is essentially two chocolate malt biscuits, coated in a thin layer of milk chocolate, with a chocolate cream filling right down the middle.

There's a lot of chocolate in one small biscuit, but in the U.S. you can get flavours like "Chewy Caramel" and "Dark Mint" -- the latter not available to Aussies.

But Australians make it up for having umpteen varieties of Tim Tam. Currently, there's white chocolate, pineapple, espresso martini, and honeycomb varieties, to name a few.

Unlike the yeast-based spread Vegemite (another Australian culinary icon), the Tim Tam doesn't polarise opinion. It's a familiar experience if you've ever had an ice cream sandwich, or an Oreo cookie.

How to eat Tim Tams

Yep, there's more than one way to eat Tim Tams.

The most popular method is to unknowingly eat through a whole packet of the biscuits, which is incredibly calorific but oh so good.

Otherwise you can try a "Tim Tam Slam," which treats the biscuit as a drinking straw for a hot or cold beverage of your choice.

Most people like to pair it with Milo, a chocolate malt drink, but you can certainly pair it with milk, coffee or even tea. Here's how it's done:

The Tim Tam is also an excellent accompaniment for cakes, either as part of the filling or as a decoration in place of icing.

Make a Tim Tam-laden cake in Australia, and you'll be sure to win friends. Or just people who want a slice.

You can even improve ice cream by sprinkling crushed Tim Tams on top, or do the same to your iced coffee or milkshake. It'll change your life.
