Wonderful change to the everyday burger!!! I made 1/4 of the amounts, for my lunch, which I just served with some chips. To me, the soy sauce was more then enough for basting the burger and would cut that back next time, but definitely makes/flavors the burger. I couldn't find a poppy seed hamburger roll, so just used my store's bakery, Chicago Hard Roll, that I toasted. I liked it as written, but enjoyed it even more with some mustard and onions. Thanks for sharing the recipe. Made for Spring 2013 PAC.
