I found this in my pantry the other day. I don't know who the Tim Tam fairy is in my house. I'm not a fan of dark chocolate but I thought "Hey, Tim Tams." The dark chocolate flavour is not as bitter as I expected. As for the rum & raisin flavour - well, I guess maybe I tasted some raisin in there somewhere. I could certainly taste some sort of fruity sweetness. I'm not sure what "rum & raisin" together should taste like so don't know whether the flavour was faithful to its origins.
