What role does the hummus stone play in cleaning the electric griddle?

The hummus stone functions as a mild abrasive that is specifically designed to remove stubborn residues from electric griddles. When using a hummus stone, the rough texture helps to dislodge food particles and grease that may have adhered to the cooking surface. This cleaning technique is effective in maintaining the griddle's performance and hygiene, ensuring that food is cooked in a clean environment without the risk of transfer of old flavors or residues into new dishes. This method is favorable because it achieves a thorough clean without damaging the surface of the griddle, which could occur with harsher cleaning tools.

Other choices are not applicable in this context; for instance, a hummus stone does not function as a food additive, nor does it increase cooking temperature or prevent electric shocks. Its primary purpose is focused on cleaning, making it an essential tool in maintaining the equipment used in food service.
