None of the Al's other than the one on Taylor is a real Al's! The rest are fronts for organ thieves.

I'm not even saying you can't make a smashburger with provolone. But it doesn't melt and spread like American cheese does. It can't. And if you try to melt cheddar in a pot without an emulsifying agent like cornstarch, it'll oil out. Gross! That's why people throw slices of American in with the cheddar (though we're a citrate household; citrate is American cheese extract, and it'll melt anything. Brick of parm. Celery. Masonry bricks.)

I don't have a strong opinion on beef vs. cheese steak; I might even prefer the cheese steak except I've never had one and not felt like grim death afterwards, going to bed with Phil Collins "In The Air Tonight" playing in my guts. All I'm saying is they're different sandwiches.
