Great flavor. I used roasted garlic - really mellow. - The musrooms in the burger gives an added taste treat Into my favorite burger cookbook it went!
As far as I am concerned, these are the best burgers I have ever tasted!! I think pork has better flavor than beef, if you "doctor" it up some. My husband and I both loved these. I used 2 lbs. of ground pork tho, instead of the 1 lb., 1 egg, 1/2 8 oz. pkg. mushrooms, 1 small onion, 2 t. minced garlic (out of the jar, that I smashed with a pinch of coarse salt), 1 t. black pepper, 5 T. soy sauce and then grilled them. YUM!! Thanks for sharing!
