I usually fry them when they're frozen and they turn out ok. I'm used to grilling them thawed though so I'll have to make an adjustment. I think I might move'em off to the side a little bit to thaw in the grill for starters, then move them over under the charcoal to get some slight burn to it. We'll see how it goes...
Currently I've got some burgers, ABTs, onions, and a foil wrap of garlic cloves and onions about to head on the grill. Can't wait to see how it turns out
Ive cooked thousands of frozen burgers. I've catered a ton of bbq's and when you r cooking hundreds of burgers, frozen is the easiest way to go. Cook to your desired internal temp and viola!.
Institutional burgers that are available at Sam’s and Costco are fine from frozen solid to fully cooked. Use a hot fire and cook them fast. We can cook a several cases an hour when the fire is right!!
