For the food historians, I was wondering, with the proliferation of Sriracha, have there always been trendy flavors or is that a fairly recent phenomenon due to the popularity of foodie culture in the last decade?

Sorry, we don't allow throughout history questions. These tend to produce threads which are collections of trivia, not the in-depth discussions about a particular topic we're looking for. If you have a specific question about a historical event or period or person, please feel free to re-compose your question and submit it again. Alternatively, questions of this type can be directed to more appropriate subreddits, such as /r/history or /r/askhistory.
