I remember once years ago a friend went to the US and brought home some Reeses Peanut Butter cups. Ohhhh, they were soooo YUMMY!!
Then, some bright spark invented them here is Australia, and they are horrible!! I much prefer the US ones.
One thing that comes across my mine was a recepie I posted on another site a few years ago, and it called for Malt Biscuits. I didnt know that in the US, you dont call them biscuits, but you call them cookies lol. I had so many people ask me what a bisuit was it was really funny, and then I was asked Malt biscuits.....seems you cant get them in the US or Malt cookies. We get them here, and they are really yummy.
