What is the first step when dropping batter products?

The first step when dropping batter products is to rake the batter. Raking the batter ensures that it is evenly mixed and has the right consistency for cooking. This step is crucial because properly raked batter contributes to a consistent coating on the food, which results in a better texture and flavor once fried. It prepares the batter for the next stages in the cooking process, such as coating the products, which would follow after ensuring the batter is prepared correctly.

In the context of the other choices, while coating the products, heating the oil, and preparing the cooking area are all essential steps in the cooking process, they happen sequentially after the batter has been raked. Raking is a foundational step that can significantly impact the final product's quality.
