Chill your cheese for at least 30 minutes before grating, and consider freezing it for 10-15 minutes beforehand for even better results. Use a chilled grater as well.
The key to grating cheese without it becoming a sticky mess is temperature control. Friction from grating generates heat, which softens the cheese and causes it to clump and stick to the grater. Here's a step-by-step guide:
Chill the Cheese: Place the cheese in the refrigerator for at least 30 minutes before grating. This firms up the cheese and makes it less likely to melt during the grating process.
Consider Freezing Briefly: For softer cheeses, consider placing the cheese in the freezer for 10-15 minutes before grating. This will make it even firmer, but be careful not to freeze it solid.
Chill the Grater: Place your grater in the freezer for about 15-20 minutes before grating. A cold grater will help to keep the cheese from warming up as quickly.
Grate Quickly and Efficiently: Use a firm, even pressure and grate the cheese in one direction. Avoid going back and forth, as this generates more heat.
Lightly Coat with Starch (Optional): For very soft cheeses, you can lightly toss the grated cheese with a small amount of cornstarch or potato starch to prevent clumping.
If the cheese starts to get sticky while grating, stop and place both the cheese and the grater back in the freezer for a few minutes to cool down before continuing. This will prevent a frustrating, clumpy mess.
