Wow!!!! This is by far the most moist, flavorful hamburger I've ever had, bar none! I doubled the recipe, DH grilled 8 and I froze 8 in pairs for the kids to pull out and cook whenever they are hungry. DH couldn't get over the flavor, ate two and wanted a third, but thankfully resisted. This will definitely be my go-to recipe for burgers and I will, without a doubt, get rave reviews every time they are served. Thanks for the post.
