RE: French fry topping
MMMmmmm, fries fresh out of the hot oil! And I haven't had breakfast yet...
My fave is white vinegar and salt, but I'm Canadian.
My introduction to poutine was when I was seventeen, and went on an exchange trip to Sherbrooke, Quebec. My exchange partner described it as french fries with barbecue sauce and cheese curds. "This," I thought, "is going to be delicious!!" We went to the local Woolworth's cafeteria and Olaf bought some for us to try. I was disappointed, because it's not BBQ sauce, it's brown gravy. (I knew I shouldn't have trusted him because, earlier, he told me that he was making "creeps" for dinner! He meant crepes.)
Many Americans ask me about poutine. It's mostly a Quebecois thing, but you can get it outside the province. Last summer I discovered that some locations of Harvey's (a fast-food hamburger chain in Ontario) carry poutine.
Thank you all for so many good suggestions.
