I'm going to be in Paris for the first time for a long weekend and have set aside one day to shop. Whenever I go to Italy, my favorite thing to do is find a good grocery store and roam the isles finding all kinds of fun things to bring home for myself (I love to cook) and as gifts. Things as simple as olive paste or imaginative bullion cube flavors make me so happy. So here's my question -- what would you bring home from France? I've heard a lot about mustards there, any specific brand recs? How about sweets? Any great candies? Really, just tell me any little yummy things you would stash in your suitcase (to be checked, of course, since it seems like most things these days aren't making it through as carry ons) if you were going to be in Paris. Also -- any great grocery store recs? Thanks in advance!!
