I was told that Wendy’s uses leftover cooked hamburger patties in their chili. That kind of weirded me out and I don’t order it any more.
I worked there many moons ago, and that’s how it was done. The burgers were just on the grill a little longer than is ideal, then they were wrapped and put in the fridge. Nothing too weird about it. And their chili sure did taste good!
You are right, thats how the do it. They have the patties cooking and when they dont get used and end up over cooked they take them off the grill and refridgerate them. When chilli cooking time comes they take the saved cooked 100% beef patties and add them to their chili base.
Food and people getting weireded out happens, weirding out is really a personal thing and you are still ok to be weirded out by anything.
