What is the secret to making the perfect grilled cheese sandwich?

For the love of all things cheesy, do not use that pre-shredded abomination from the supermarket. Make your own shredded mozzarella, and use a blend of cheddar and gouda for the ultimate flavor.

But wait, there's more! Use a cast-iron skillet, not that non-stick nonsense. It's like trying to make a soufflé in a ziplock bag.

And don't even get me started on the importance of using high-quality, artisanal bread. You can taste the difference, trust me.
