They’re most of the way there but fall a bit short of a real Tim Tam. I find the chocolate has a slight sourness to it compared to the original (as if they let an American pick the recipe) - not enough to stop me eating them but enough to reduce the normal Tim Tam desire to rip through a whole packet.

The Choceur chocolate blocks however tend to be a quite acceptable replacement for Cadbury and even Whittaker so not all hope is lost for more affordable chocolates.
