Favorite Swedish food

Here are some of my favorite Swedish food that is available here in the US (and mostly only at IKEA, of course). Do you seen anything in common among these items? The only thing I know is that they are GOOD. In order: Slotts mustard, Wasa crispbread, Abba anchovy-style herring, Felix pickled beets, smoked roe spread (kaviar) and Kung Gustaf sardines in tomato sauce. Mmmmmm!
Those of you that live in Sweden might not think these are special, but they are!
