Once on a flight from Hawaii I noticed they served us cans of Coke which I think were on the flight from Japan. I immediately looked as saw "SUGAR" as the ingredient. I asked the stewardess if I could have more (and pointed at can and showed her what I needed! She said she noticed Coke tasted different overseas but thought it was the water....)

Now live in Hawaii and there does not appear to be Kosher aisles in my supermarket.

However, we DO have an abundance of cane sugar. Just walk down the field and pick up a piece of sugar cane. Can't get less HFCS than that!
