Step-by-step explanation:
To prepare the breakfast grill or griddle for use, the appropriate action would be C. Preheat for 15-20 minutes. This allows the grill to reach a stable cooking temperature and ensures even heat distribution. While it's crucial to ensure the cleanliness of the grill surface, the correct temperature is also necessary to prevent the growth of bacteria, which can be verified using a thermometer as per Figure 4.7.7. While option A suggests setting the temperature to 275°F, this may vary depending on what you are cooking, and 275°F is not typically the preheating temperature for a grill. Option B is important for cleanliness, but the grill must be preheated before this step. Lastly, option D. says to spray a thick coating of canola oil on the grill surface, which could be too much and result in greasy food. Always apply oil sparingly, after the grill is preheated.
