Yes, in the npub Pro page, you can specify hashtags. So technically, what it's doing is it's searching for anything that is tagged with #nostrcooking, which is a hashtag that automatically gets appended to zap cooking posts. And in my other menu tab, anything that I tag with #Foodster shows up. 

 Just today to test this out I posted a recipe this morning and it almost instantly showed up on the Npub Pro page which is pretty slick.
