[i]I can only speak from my very limited experience, but the big difference to me was the ingredients. Some of the ingredients used in American cooking, are not available in Scotland.
One example. When I was trying to prepare a Meatloaf, or even meatballs for that matter, I was unable to purchase Bread crumbs with all the seasonings already in it. For instance, 4 Seasons Italian bread crumbs are full of all sorts of stuff to give it a particular flavour. When I asked, I was told they make their own bread crumbs and season it to their liking. Since I have no real understanding what 4 Seasons puts in their stuff... I was at a loss.. lol..
I also add a Jar of Turkey or Chicken gravy to my meatloaf. It helps give it some moisture, making it so much better. I couldn't find that either. To make your own gravy (brown sauce) I was unsure what to use to make it thicker. Here I would have used corn starch or something, but at that point.. lol.. I was like.. Oh god.. lol.. nevermind.. lol..
Needless to say the meatloaf I made was Awful.. lol..
