Need to delete all recipes stored on my iPhone.

I have several dozen recipes on my iPhone and I'd like to delete them all.  (They're safe on my mac)  The only way I've found to delete recipes is to open, delete, confirm delete, repeat.  I don't want to do that over and over and over...  Please help.

I figured it out.  I simply deleted then reinstalled the BS app.  (There ought to be a better way)
