Effervescent Bacon Drink Tablets

One of my wife's friends is living in the US. She's been there for about a year. When she first arrived she sent back some stuff to her mother, including these Effervescent Bacon Drink Tablets. She just got back for a holiday, bearing in mind she left a year ago. I finally got the tablets now! But at least I got them. So they may be a little past their sell by date, but what can go wrong? They're Bacon pills!
I first mentioned them here when she took a photo to let me know what she was sending back.
