Penzeys, but have since found McCormick and Spice Island brands at the Superfresh or Giant.
Before trying it, I didn't know what the fuss was all about. I always thought standard paprika - the kind one sprinkles on top of devilled eggs as a garnish - had little or no flavor. Smoked paprika, on the other hand, lends a lively and of course smoky flavor to food. I like to put it on basically everything, because, like everyone's favorite similarly smoky-flavored pork product (that would be BACON), it's good in everything. Sure, put it on devilled eggs, and in egg salad. But it's great in chicken salad, in chili, and in a dry rub for ribs or steak or shrimp. Or vegetables. Anything that calls out for a bit of smokiness.
