The Technique
Buy cheese in block form and shred it yourself on a box grater immediately before use. It takes 90 seconds and the difference in melt quality is dramatic. Fresh-grated cheese melts into a smooth, cohesive layer. Bagged pre-shredded cheese melts into an uneven, slightly greasy, separated mess — if it melts fully at all.
Why It Works
Commercial pre-shredded cheese is coated with cellulose, potato starch, or other anti-caking agents to prevent the strands from clumping together in the bag. These coatings are inert from a flavor standpoint, but they interfere significantly with melting. They create a barrier between cheese proteins and fat, preventing the smooth emulsification that makes melted cheese flow and stretch. Fresh-grated cheese has no coating — protein and fat interact freely, resulting in the kind of molten, stringy, completely uniform melt that makes a truly great grilled cheese or hot sandwich.
When to Use It
For any application where the cheese will be melted — grilled cheese, quesadillas, hot subs, egg sandwiches, cheesesteaks. Pre-shredded cheese is fine in cold applications where the anti-caking agents don't affect the result, but for anything heated, block cheese grated fresh is a material upgrade. Mozzarella, cheddar, Gruyère, fontina, and Monterey Jack all benefit enormously from this approach.
Pro Tips
- A cold block of cheese grates more cleanly than a room-temperature one
- A food processor shredding disc handles large quantities in seconds
- Shred directly into the pan for even distribution over a wide surface
- Freeze block cheese for 15 minutes before grating for the cleanest shreds
