NATIONAL POPCORN DAY: All this puddle-forming weather just happens to be falling on January 19th -- National Popcorn Day, for those of you keeping track at home -- which seems fortuitous to us. One, because we suspect that people will be making for the movies, weekday workday or not, and the connection between popcorn and movies dot dot dot. And two, because we also suspect that people may be DVDing it in droves this week, in addition to see flicks in the theater. Time for a make-your-corn-at-home kit. We found this seasoning-savory popcorn set at Williams-Sonoma..EXTRA BUTTER: It's $26. Extra Chili Lime flavor for us, please.
