מיט װאָס עסט מען דאָס? ?What on earth are these

Did I buy these at the farmers' market, or did The We'an catch them playing Pokemon Go?
I cooked some of them and connected one to the mouse-port on my computer, unless I made up that last bit.  I will update this post with a recipe soon, but first post your guesses in the comments.  If you are reading this on email, click here to comment.  In addition to immortal fame and glory, the winner will get a little lagniappe from me.
