Wow!
This is a really great thread!
For the folks that like American pancakes, you need to try Carey's Sugar Free Maple Syrup. It can be a little hard to find at the supermarkets, and is sometimes with special diet food instead of with the syrup.
It is absolutely as good as regular maple syrup. 1/4 cup has 25 calories.
It would be really great to try Southern Corn (Maze) Bread. If your purchase something like White Lily Corn Meal, a good recipe will be on the side of the package. Cornbread is best prepared in an iron skillet. Corn meal is different outside of the Southern U.S. in case you want to try it in other parts of the country. Cornbread is fantastic eaten right out of the oven with butter.
An authentic Southern U.S. meal would be fried pork chops, fried okra, squash, corn on the cob, and corn bread. Wash that all down with Southern iced tea! Lemon ice box pie, coconut pie, or pecan pie would be ideal Southern desserts.
(Pecan will have many pronuncians around America.)
I pronounce it pu-cahn. Others say pee-can. I've heard pu-can, and pee-cun.
For a chain, Cracker Barrel restaurants have the most authentic Southern U.S. food.
Sudafed is great for headaches, but you have to sign for it, as it is being abused by druggies.
Many Americans think Snickers are as good if not better than Reeses.
1 other thing, there are these small candy packages at convenience stores called Laffy Taffy. Get the Banana. Its so good, its addictive. For the Little Debbie lovers - try the Oatmeal Cream Pies.
I hope that I have listed must have U.S. items.
