Wow. Those are all US staples. Though I'm sure if you rattled off the items that are staples in your pantry, I'd be... huh?
heavy cream, dairy product produced by skimming butterfat from milk
light corn syrup, clear glucose syrup (dark corn syrup has molasses added)
vanilla extract, alcohol solution infused with vanilla beans; used in almost every American dessert recipe
large loaf french bread bread or challah, wheat breads; challah is sweeter and eggier (one of my favorites)
half-and-half, dairy product lighter than cream but heavier than milk
caramel sauce, the sauce made in the first part of the recipe
