We just so happened to have the main ingredients for this recipe, which actually led to me on this search. I had had pork infused burgers whilst living in Thailand so I knew it wasn't unheard of. I put my fiancee in charge of this because I had to prepare other things for our fourth of July party we hosted, and I was blown away. These are easily the best home made burgers I've ever had. I was even scared they were over cooked, but the pork must've saved the day. They were phenomenal. My partner is a baker and so followed this recipe to the T. Only hiccup was an unoiled grill (she didn't know). so a few of these puppies stuck and fell apart. Oh, only other issue? Everyone else loved them so I only got to eat half and there were no leftovers!
